I have a rare book that lists BOETTGER/BOTTGER -BOTTCHER families from 1667 to the present day. They lived in BECKEDORF and nearby communities. The church
records were recorded in the nearby SINSTORF church.
There are many families listed. I will be willing to search the
book if you suspect your ancestor may have come from
this area. The villages are located just south of the city of
Hamburg/Harburg.
