Hello,
This is just for clarification, as I am responding to a post from last year and I think we had corresponded on this.

The William Lewis Ralph b about 1836 TN, who moved to Mississippi County, Arkansas is a different person then the William L Ralph of Sumner Co., Tn who moved to Polk Co., Mo.and served in the 1st & 4th Consolidated Missouri Inf

They were from different lines both though from Tennessee.
Lee Ralph
