We have the same information on H.D. I did find on harrigan family tree that William collier (1814-1850) married Isabella Elkins. Married in Lee County, went to Red River City, Texas where William evidently died. She married John Honeycutt 1854 in Red River City. Cynthia and David Collier also lived in Lee County, Red River City and then they all were in Williamson County, then to Coleman county. I believe the Mary Jane Elkins and Elias Elkins that were living with them are Cynthia's half siblings, just a guess. Mary Jane and Elias must have stayed in Red River City. Mary Jane married George Blair. Maybe Isabella was H.D.' aunt.
Cynthia later married Taylor Smith, Jr (Shug) in 1854 in Silliamson County. Tehy are both buried in Glen Cove Cemetary, Coleman County, Texas. Still searching for H.D.'a parents. Hope this helps some. Helen
