Starting with my Great-Grandmother...

Alma Elizabeth Clark born 26 Dec 1903, TX to William Henry Clark born 17 Nov 1854 in Indiana and died 4 Jan 1934 in Collin Co. Texas. His wife Amanda Dugan was also born in Indiana March of 1862 and died 5 May 1949. From the information that I have William Henry's parents were from Tennessee and I know nothing about the parents of Amanda.
