Tina, I think we definitely have a match. I show that Solon married Mabel around 1920 and was widowed with three children at that time. I have 1879 written down next to Mabel and Robert Killough on my notes, but don't remember if it was birth or marriage. Would have to be birth date tho. Would love to see your pics. I have Solon traced back to Reuben Riggs and Mary Crawford, but know nothing of your Mabel or Minnie. However Mabel would have had to have been around the children- which Wilmer Vaud (my grandfather) was one! My email is: firstname.lastname@example.org
if you would like to exchange more info!
