Hi - I am also interested in the Maskow/Mascow family from Roggow. Christoph Maskow married Caroline Krueger in 1826, and their daughter, Hanne Louise Friederike Maskow, born 1835, was my husband's great-great grandmother. She married Carl Beske from Immenthal and, with their 9 children, they emigrated to America in 1885.
I have as a possible father of Christoph Maskow a Conrad Maskow of Roggow. Do you know anything about this line? Christoph appears to have married Ann Sophie Giese first. My guess is she died in child birth.
Any information you have would be greatly appreciated!
