Hello Teresa,
my gggrandmother is Emma Sophie Wilhelmine Steinkamp. She was born in 1842 in
Westerstede. She had a brother Fritz Bernhard and a sister Friederike Marie
Mathilde, born in Leer. Westerstede is in the district Ammerland in the west
of Oldenburg and Leer is in East Frisia. Also there are a few Steinkamps in
other parts of the former land of Oldenburg. May be your Steinkamps are
related to my ancestors.
Best wishes from Hannover, Germany
Gunter
