My maternal GGGM Sarah M. (Spencer) Thomas had sibling Abbie M. (Spencer) Dubois b. 5 Aug 1838 in Ulster County NY USA, "Abbie M." routinely uses her middle initial in USC records, but a second Abbie Dubois appears in a nearby town in the 1870 USC. THUS: 1860 USC Abbie M. Dubois in Twn/Saugerties with husband Wynesma (sp?) Dubois b. abt 1835 and children incl a "Kate". 1870 USC Abbie M. still in Twn/Saugerties with Wynesma and children incl a "Kate" .... also in this family is a Margarette Dubois b. abt 1815. HOWEVER, there is another Abbie Dubois listed in nearby Twn/Hurley with a husband George Dubois b. abt 1834 plus their children. I don't find this duplicate "Abbie" in other records. 1900 USC Abbie M. widowed and in Saugerties. 1910 USC Abbie M. widowed and in Yonkers - NY City. So who is this other Abbie Debois in 1870 ? Based on routine use of middle initial I believe I have the correct one for my purposes.
