Hello cousin, I am searching for info concerning Harriet Silsby who was the daughter of James W Silsby and Harriet B Shaff. Harriet was born in Tompkins co. NY about 1846, according to census records I have researched. In 1865 census Harriet and William Cogsdell are listed as living with her father in W. Almond Alleghany co. NY. William Cogsdell is from Cattaraugus Co. NY. I have found no listing for her after that date. I believe we are researching the same person, so that makes us cousins. Hoping and anxious to hear from you.
