The father of Henry Andrew Dankers was also Henry Andrew Dankers (Sr.). Sr. was born in 1798, also in Hannover. Otto Dankers (Danckers) was born in 1812, so he cannot be Sr.'s Father. I will admit to wondering if Otto is a cousin or uncle, but have not yet been able to find any familial information on him. I am hoping, after two years, that someone else may be searching?
