I have a very small amount of information on your Black lineage that you probably already have.Hamlin (sometimes seen as Hamline) Black married Mary Catherine Bilberry in Texas in about 1890.They had only one child that I can find who was Elbert Madison Black (b. 20 May 1893 in San Angelo, Tom Green County, Texas and d. 21 September 1982 in Houston, Harris County, Texas).Elbert Madison Black married Alice Allene Sowders on 9 July 1919 in Morgan, Bosque County, Texas, and they had two children of record, i.e., Delvenia Black (b. 6 March 1922 in either Bosque County, Texas or in Eddy County, New Mexico and d. 19 April 1922) and Albert Perry Black (b. 19 August 1923 in Iredell, Bosque County, Texas and d. 21 March 1996 in Lane County, Oregon).I have no information on who Albert Perry Black married or if there may be children still living from such a marriage.Mary Catherine Bilberry (b. ~1867 in Texas) was the daughter of John C. Bilberry (b. 12 April 1829 in Tennessee) and Elizabeth Unknown (b. ~1834 in Illinois).John and Elizabeth Bilberry had two children other than Mary Catherine, i.e., Martelia (b. ~1871 in Texas and d. unknown date in El Paso County, Texas and married John Couch Abel) and William (b. ~1863 in Texas and married Leonadas Unknown).John C. Bilberry was the son of John Bilberry (b. ~1807 in Tennessee) and Catherine Unknown (b. ~1806 in Tennessee).Afraid that this is all that I currently have.
