Looks like if anything, my Martha was your Frederick's sister or cousin. She was born between 1830 & 1836 in New York State. She married my great-great-grandfather William BISHOP in 1850 in Rochester. They had a son named William, in 1858. Later, moved briefly to Nova Scotia where my great-grandfather Alfred and one of his sisters, Wilhelmina, were born. Later they movef back to New York, this time to Palmyra, in Wayne County. Finally, they moved out to Washington State by 1870. Of Martha's family all I know is the surname RAPP (from Wilhelmina's birth record), and that her father was from France (possibly Alsace?) and her mother from New York. I don't know if this information is familiar, but if it is, please get back to me. Thanks!
