I'm doing my best to join you as a Tougas dit Laviolette descendant. Here's what I have so far:
my great-great-grandmother Emily "Emma" Victoria Burdalow b. 10 Oct 1871, Illinois, daughter of Mitchell Burdalow (possibly Michel Bordeleau, son of Pierre Bordeleau and Julie Poitevin dit Arpin, but I haven't seen the proof yet) b. abt 1836 and Barbara Tougas dit Lavalette b. 5 Jun 1841, daughter of William Tougas dit Laviolette b. abt 1809 Illinois and Julie Ann ____
In the 1850 census, Lawrence Co., IL, page 34: William Tougas 41 Julie Ann 31 Frances 16 F Barbara 11 F Elisabeth 2 F
On the next page, John Tougas 32 Frances (Moese) 30 Jane 7 F Felix 5 M Paul 2 M Gabriel 3/12 M Michael Burdelow 14 (this may be my ancestor Mitchell who married Barbara)
I'm wondering if William is the son of William, brother of Augustus, Joseph, and Francis, of Vincennes and Illinois. Anyone know about William and John?
