My SOMMERFELD ancestors lived in small villages in the rural areas to the south east of Danzig in Tiegenort, Stobbendorf, etc. (Gross Brunau). Is there any pattern based on geography that might suggest which military units they were conscripted into to do their mandatory service? I doubt that they were professional soldiers or officers. If I can find the unit, perhaps I can find a bit more about my ancestors.
Thanks in advance. Grant
