Sarena on Family Tree Circles

I am looking for any information anyone would have on my great grandmother's mother or father. Theodore Wilson Patterson born around 1853 and Donce Coates Patterson born around 1855. My great grandmother was the youngest of four her name was Myrtle Mary (Patterson) Martin. Any information on where either was born or buried.

I also know that Theodore remarried a Cory Jill (Sutton) Patterson in 1897. As I can not find any birth records on my great great grandmother I am not 100% sure which was her mother.

Any information on how to locate any of this information would be greatly appreciated.
