My Jaycox relation is Henry Jaycox, b. 1824 in New York who married Sophia Godfrey, b. ca 1827 in New York to Elisha & Polly (Barden) Godfrey.
They had James Jaycox born ca 1853 in New York & Henrietta Jaycox (I have a photograph of her with her husband, Cortes Hull taken ca 1880) born ca 1851.
I believe the parents of Henry Jaycox are John & Sara/Sarah of New York.
