Margaret was the wife of Ephraim Thompson, who died in 1834 in Daviess County. Both Ephraim and Margaret were born in Maryland, probably Cecil County. Margaret was living with her son John Thompson, his wife Elizabeth, their sons Ephraim, 16, Edward, 14 and William, 10, in the 1850 census, but not there by 1860 census. I'd appreciate any help. Margaret and Ephraim's youngest son, Andrew Thompson, b 1816 or so, was my great great grandfather.
