Frank Pendergrass - Tennessee

I have 2 death certificates.

The first one is for my ancestor, Frank Cheatham Pendergrass who died 7/18/1946 in Nashville, Davidson County, TN.He was born 4/12/1872, and was a son of Ensley Pendergrass & Lorena Donaldson/Donnelson.

I'm looking for any other ancestors/descendants of this man.
**************
The other death certificate is also for Frank Pendergrass.It appears he was born 11/27/1847, and he died 1/10/1927 in Nashville, TN also, but it looks as though he lived most of his life in Hickman County, TN.His father is listed as Manley Pendergrass and his mother is:Mary Tidwell.

I'll be happy to share any information on either of these Pendergrass gentlemen.Does this fit with anyone out there?
