Over 70 people with my -at name (and its few variations) in the 19th and 20th centuries have been located in the former East Prussia in the Gumbinnen and Konigsberg Administrative Districts. Someday there may be a connection to the three 19th century families from Wylkowiszki in the Russian Empire who immigrated to the United States between 1905 and 1908.

Specific locations in the seven kreise where people with my –at name lived in the Gumbinnen Administrative District are presented in the geographical proximity they were researched— Kreis Stalluponen, Kreis Gumbinnen, Kreis Insterburg, Kreis Darkehmen, Kreis Goldap, Kreis Ragnit, and Kreis Pillkallen.

Gumbinnen Administrative District
Kreis Stallupӧnen is directly west of Wylkowiszki. The area to the east is present day Lithuania. Eydtkuhnen, the first clue I was given as to the possible East Prussian location of the birth of the father of one of the three -at immigrants, and a location that was also known to her grandfather, is a border crossing.
A Spurga (no final t) was located in Kattenau, but no other people with my –at surname have been found in the following parish registers: Bilderweitschen, Eydtkuhnen, Enzuhnen, Goritten, Mehlkehmen, and Stallupӧnen. The result of this two year search appears to be a family story that cannot be proved with records.
Additionally, research including the maternal names of Ber (Berz), Gudat (Guddat), Henning, Keller, Kuczynska, Raudinat, and Walat (Wallat) have not resulted in any direct leads.
Spurgats were located in the city of Gumbinnen, today Gusev, Kaliningrad Oblast, Russia, and two other locations in Kreis Gumbinnen in the 19th century.
In the Gerischkehmen parish two Spurgat names were also located on a marriage index in 1813 and 1815, (FHL INTL Film 1812746, Item 4), but not in the birth or death index. The marriage records were not on the film. Today Gerischkehmen is known as Priozernoe, Kaliningrad Oblast, Russia.
In the Nemmersdorf parish two Spurgat births in 1806 and 1807 (FHL INTL Film 1812658) and one death in 1806 (FHL INTL Film 1812660, Item 3) were located in Szublacken, today Luzki, Kaliningrad Oblast, Russia. A marriage in 1837 (FHL INTL Film 1812746, Item 2) was located in Tutteln, today Sycevo, Kaliningrad Oblast, Russia.
The Spurgat name was located in the city of Insterburg and two other locations in the Insterburg parish: Kummetschen, today Zelenyj Bor, and Jessen, today Solovevo, both in the Kaliningrad Oblast, Russia.
In the Pelleninken parish two variations of the Spurgat name have appeared. In Pelleninken, today Zagorskoe, Kaliningrad Oblast, Russia, a Christoph Spurat (without a “g”) was located. In Neunischken, today Privolnoe, Kaliningrad Oblast, Russia, a Christup “Spurga” (no “t”) was also located. More research will clarify the pertinence of these surname variations.
See https://suwalkigermans.wordpress.com/2017/01/01/research-2012-2015-post-17-spurgat-research-in-kreis-insterburg/ for more information on Spurgats in Kreis Insterburg in the 18th century.
Research in the Insterburg parish is ongoing.
One Spurgat was located in Kreis Darkehmen.
Szilchen, the village associated with the Spurgat name, was not located on any map. (Two other nearby locations with similar spellings–Szallgirren and Szabienen– were determined not to be the correct village.)
Spurgats identified in nearby locations include: Didlacken, Kreis Insterburg, in the northwest and Goldap, Kreis Goldap, in the southeast, both sharing partial borders with Kreis Darkehmen.
Two families of Spurgats were identified in the city of Goldap in the mid 19th century.
A Spurgat was also identified in Regellen. A third possible location of a Spurgat was Schillinen.
Tollmingkehmen and Gawaiten are now in the Kaliningrad Oblast, Russia. Gross Rominten and Goldap are now in Poland.
Kreis Ragnit has had many boundary changes: in 1818 the Congress of Vienna established borders from surrounding areas, north and south of the Neman/Nemanus (Memel) River. In 1875 and 1876 three more rural municipalities were added to Kreis Ragnit.
In 1920 after the Treaty of Versailles a Kreis Pogenen was formed from some areas of Kreis Tilsit and Kreis Ragnit. In 1922 areas south of the Neman (Memel) River were organized into Kreis Tilsit-Ragnit. Areas north of the river became part of Lithuania where the villages of Szugken/Zukai, Wischwill/Viesvile and Schmalleningken/Smalininkai are still in what was known as Lithuania Minor.
Spurgats have been located in Szugken and Schmalleningken.
Today areas south of the river are in the Kaliningrad Oblast, Russia.
The city of Pillkallen and the parish of Kussen are identified locations.
A few Spurgats lived in Kreis Pillkallen in the late 19th and early 20th centuries.
