Hi Ron,
My husbands' great grandfather was Henry Joseph Viaene in that area of Idaho too!
Who are your parents? Feel free to email me directly if you like. We have Viaene's in WA state who are from Henry 's line as well.His second wife's name was Irma Van de Viaene(sp?). Does that ring a bell with you?
I hope to hear from you and take care,
Shannon Viaene
