Dear researchers

My family research has come to a halt
I have some information about Moses BLANCKENSEE or BLANKENSEE born in
Wielun (was Filehne) Poland in 1810
I am curious about his father, Lewin Moses LEVY
Has anyone information about this man and where and when was the name
changed? kind regards
