Most of this site’s guides lead to Vilnius, where the Lithuanian State Historical Archives hold the Catholic and Russian-era books. Families from Lithuania Minor are the exception. Their records were written in German, kept by Lutheran parishes in Prussia, and now sit mostly outside Lithuania. If your ancestors were Prussian Lithuanians, or came from the Klaipėda corner of the country, this guide explains why the usual advice does not apply and where Lithuania Minor genealogy actually begins.
Who lived in Lithuania Minor
Lithuania Minor, in Lithuanian Mažoji Lietuva and in German Kleinlitauen, is also called Prussian Lithuania. It was a region of Prussia where Prussian Lithuanians, known as Lietuvininkai, lived, and it is now divided between Lithuania and the Kaliningrad Oblast of Russia. A dictionary entry describes it as a historically Lithuanian-speaking region, now politically mostly in the Kaliningrad exclave, with small parts in Lithuania and Poland, and often taken to mean only the portion that lies in Lithuania.
That last point is the heart of the problem for researchers. The part that is inside the Republic of Lithuania today is small, and the family you are looking for may have lived in what is now Russia. So the first step is to learn which side of the modern border the village is on, using the place-name methods in our guide to Lithuanian place names, parishes and dioceses. The wider regional picture is in our map of Lithuania’s historic regions.
Four administrations in one family tree
A family on the Klaipėda side of Lithuania Minor could have records written under several governments within two or three generations. The table shows what the sources let us say, and where we could not confirm the details.
| Period | Who governed | What it means for records |
|---|---|---|
| Until the First World War | Prussia, then the German Empire | German-language Lutheran church books. The FamilySearch catalog lists parish registers for Memel (now Klaipėda) from 1614, in German. |
| 1923 to March 1939 | Memel Territory, an autonomous part of Lithuania under the Memel Statute of January 1923, with the districts of Klaipėda, Pagėgiai and Šilutė | We could not confirm in which language local records were kept in these years. At least one Archion listing for a Memel congregation is labeled with the Memel Territory years 1920 to 1939, so do not assume the church-book trail stops in 1923. |
| From March 1939 | Germany re-annexed the territory | German-era records, many of which are now in Berlin. |
| After the Second World War | The area is now divided between Lithuania and the Kaliningrad exclave of Russia | Records of the Lithuanian part may be in Lithuanian archives; records of the Russian part are a separate research problem we do not cover here. |
The dates for the territory come from JewishGen’s page on the regions of its Lithuania database, and the description of the region comes from a dictionary entry for Lithuania Minor.
Where the Lutheran books are kept
Prussian church registers did not stay in the villages that wrote them. The Evangelical Central Archives in Berlin hold roughly 6,000 church books from Protestant parishes of the former eastern church provinces of Prussia, according to Archion, the German portal that publishes them. Archion states that the vast majority have been digitized, that several hundred parishes from 112 districts are online, and that a small remainder can be read only on site in Berlin. You need an account to view the images.
A Lithuanian scholarly article reconstructing a Prussian Lithuanian family confirms the same picture. It says the surviving church books of Prussian Lithuania are held in the Evangelical Central Archives in Berlin and in the State Archives in Olsztyn, and that prewar microfilm copies of books lost in the Second World War are kept at the Saxon State Archives in Leipzig. So the question “where is the book?” can have three answers for one parish: Berlin, Olsztyn or Leipzig.
FamilySearch is the other route. Its catalog lists registers for the Memel parish from 1614 to 1944, recording baptisms, marriages and deaths, filmed from manuscripts in Berlin-Dahlem. Some early volumes are transcripts rather than originals, which matters when a spelling looks odd. The logic of entries explained in our church books guide still helps, but the language and forms are different here, and we have not compared the two formats line by line.
One Lithuanian option is easy to overlook. Our guide to requesting records lists a regional state archive in Klaipėda. We could not confirm what local material it holds for the Prussian period, so write and ask rather than assuming it is empty.
Reading a German-language entry
A few German words in the catalog headings tell you what you are looking at before you open a page. The terms below are taken from the labels of the FamilySearch catalog entry for the Memel registers.
| German term | Meaning |
|---|---|
| Taufen | Baptisms |
| Heiraten | Marriages |
| Tote | Deaths |
| uneheliche | Births outside marriage |
| Abschrift | A copy or transcript, not the original |
| Index (as in Tauf-Index) | A name index to a set of entries |
Older German entries are often written in a handwriting style that takes practice to read, so allow time and copy each entry letter by letter before you translate it. Surnames in these books are written the way a German-speaking clerk heard them, which can differ from the Lithuanian form your family used. Keep every variant in your notes, and compare the parents, sponsors and village before deciding that two entries are one person.
Refugee lists and the end of the trail
Near the end of the Second World War, many families from this area fled west. The Evangelical Central Archives in Berlin list a series of refugee records for the districts of Tilsit, Memel and Goldap, and the Archion listing we saw says that no digital copy is available. If your family left in 1944 or 1945, that listing is a reason to ask the archive directly. We did not open the series, so we cannot say how many names it holds or whether they are searchable.
Example (invented, for illustration only): A reader’s grandfather was born in a village near Šilutė, which Germans called Heydekrug, in the early 1900s. The reader searches the village under both names, finds that its Lutheran parish registers are listed on Archion, and creates an account to look at the baptism pages. The entry is in German, so she copies it first and checks the sponsors against a later marriage entry before adding the family to her tree.
Gaps in our research
- Archion’s current account rules and prices. A forum post mentioned a monthly fee, and we could not verify it.
- Whether civil registry books, as opposed to church books, survive for the Klaipėda districts.
- The language of local record-keeping during the 1923 to 1939 period.
- How many of the Berlin church books cover villages that are now in the Lithuanian part of Lithuania Minor, rather than the Russian part.
The Archion page that gives the Berlin figures is its description of the Evangelical Central Archives. The FamilySearch entry is the catalog record for the Memel registers, and the scholarly article is a reconstruction of the Mielcke family in Prussian Lithuania.
Choosing your starting archive
- If the village is now in Lithuania and the family was Catholic, start in Vilnius with the complete guide.
- If the family was Lutheran and the village lay in Prussian territory, start with Archion and the FamilySearch catalog.
- If a book you expected is missing, ask Berlin, Olsztyn and Leipzig before concluding it was destroyed.
- If the family left in the final war years, add the Berlin refugee lists to the plan.
