Hi Nita, I realize you posted this message over 1 1/2 years ago, but if you are still looking, I have some information on the descendants of George Franklin Myers, son of John Miller Myers.
George Franklin Myers and his wife Ella Prudence Kennedy are buried in Webb Chapel Cemetery in Farmers Branch which you probably already know since you mentioned that you had been to the Dallas Library doing cemetery research.
My husband is a trustee for the Webb Chapel Cemetery Association which is planning a reunion in 2002 for descendants of persons buried in the cemetery. This will be in honor of Isaac Webb's 200th birthday. Richard and I are doing the research to locate the descendants. Anyone wishing to discuss this project can email me at: email@example.com
