I haven't done this for two years! But here is what I have on my Gaby family. My great grandmother was a Gaby; Hattie Suevella Gaby. Is it possible that I can just scan this in and email it to you? I would need dates from you also to try and figure this out. But I will give you the gist of what I have without including all the children...I have pics of some of the Gabys on my tree McNabb-Bailey.
Isaac P. Gaby b. Nov. 01, 1806, d. Nov. 17, 1876 married on April 30, 1840 to Mary A. Harshbarger b. between 1820 - 1823 and d. 1882. Her parents are David Harshbarger and an Elizabeth; my research shows that it could be Elizabeth Beacher. Isaacs parents were from PA and were Isaac Gaby and Magdalen Frantz. Check info from the Greene County and Washington County Tennessee Census. Thats where they mostly were born and died. Unfortunately I believe a lot of records were lost in Greene County due to a fire.
Isaac and Mary had 12 children. According to my info, they had a son Christian Gaby b. 1831 married to a Mary Patterson June 27, 1850. Christian is buried at or services held at Mt. Valley Church in Greene County, TN. They married in Washington County.
Also a son Martin M. Gaby b. Nov 03, 1835, d. July 02, 1891 and married Sarah Cooter on Jan. 29, 1857. They Married in Greene County and one of their or both of their burials are at Mt. Valley.
They also had a daughter Mary (margaret) Gaby b. June 08, 1842 and d. July 07, 1897. She was buried at Mt. Valley as well.
