Addington's in Texas

Hi, my name is Janna Parker.I have just recently started doing research.But I think I have found my Addington's.My grandmother was Fannie Mae Addington,b:1906 in Texas and died 1977 also in Texas.Her brothers and sisters were - Ruthie Ellen, Arizona, Laura Leroy T., Frankie M., Claudie, Margeree and Clyde (?).Their father was Harmon Willis Addington m: Delia Ann Thomas.I believe Harmon was born in Arkansas in 1870 and died in Texas in 1939.His parents were Joseph Addington and Susann Thomason and his father was James M. Addington.Most of this I have gotten off the internet.Except for Fannie's family, I have pictures of the brothers and sisters together at I believe Ruthie's funeral in 1955.If this sound right or wrong please let me know.I would like to see if any cousins are still in Texas
