Might your McQUillens be Roman Catholic?Is there are Nancy or Ann married to Francis Craig (both born Ireland, married Ireland, but at least two children were married and died in WI.No knowledge of where Francis Craig and Ann-Nancy? McQuillen Craig died -- I think Francis was from Finvoi, Antrim; and the McQuillens from Dunloy, Antrim, but it is not clear.
Also, I have seen McQuillen spelled McQuillan in family documents also.
William Craig married Sarah Alice Doyle in Portage, WI 11.1.1862.
John Craig was in the Union army, and upon return to WI was likely am important Presby. minister in Eu Claire.He married at Catholic Hogan, but they were buried in separate plots. . .
