I am wondering if your Tom Campbell is not the brother to my ggg grandmother Leora Campbell. The family I have:
Andrew B Campbell Married Louisa Johnson 1853 Massac County, Illinois
1) Thomas H B ~1855
3) Leora Kanzada B 1860
4) Richard M
5) Laura M B 1866
8) John H
Andrew B was born in Tennessee/Kentucky and served in the Civil War. Laura Johnson is the daughter of Thomas and Lavina Johnson.
Both Andrew and Laura are buried at Lower Salem Cemetery in Massac County. Also, many of their children are.
