I am looking for information on my fourth great uncle & aunt John Pierce & Elizabeth A J Jones.

Uncle John was born February 1851 DeKalb County, Georgia to fourth great-grandparents Levi & Martha Ann GRANT Simpson, death date & burial place unknown.

Aunt Elizabeth A J Jones was born July 1853 Georgia death date & burial place unknown.

They were married 14 January 1872 DeKalb County, Georgia & were living in Henry County by 1900 in McDonough. Their children were:
William A. Simpson
Sarah Simpson
J ... Simpson (male, name hard to tell in 1880 census)
David Simpson born August 1882
Ralph J. Simpson born May 1887

When my third great-grandfather James Anderson Simpson passed-away in April 1918 Uncle John was still alive & living in McDonough as was Uncle William; Uncle Isaac H. Simpson was living in Ellenwood; Uncle George Monroe in Powder Springs.

Any help with Uncle John & Aunt Eliza's family would be greatly appreciated.

Thank You,
Lena
