Have you been able to find the data I posted on Rootsweb?
If this Henry Viaene is not on it, I fear I cann't help you much further. The point is that there are (at least) 3 major Viaene families , mostly in the province of West-Vlaanderen in Belgium. The family whose data I published goes back to around 1590 , and no relationship has been found with those other Viaene families.
By the way, in earlier records the name is sometimes written as Viane or Vyaene or Vianen, or Van Vianen.
