Ephraim Wilson is found as constable,. Jones Creek, Morgan Co in the July 1 1863 draft record. He is also found with brother Jonathan C Wilson in 1850 in the household of a Robert Wilson b 1819 Missouri District 59 Morgan County. This is a different Ephraim and John Wilson that is found in the 1860 household of W R Wilson ( b 1821 Alabama). Robert Wilson and Jno C Wilson are found in 1860 census in Haw Creek Morgan County.

So maybe the report of a Robert Wilson being the leader is correct.

FWIW

John R.
