I'm not related but I just did a lookup in the "McCabe List" for the name Teevan and came up with the following so I thought you and others with Teevans from Canada might be interested. There was a Barney Teevan who signed an 1829 petition stating that he was doing well in Canada. Most petitioners were asking for assistance with emigration for others in their families.However Barney was not. He was originally from Ballhays, Annagh parish, County Cavan ( 2 men and 3 females in the family)."His relations have already emigrated to Canada". [note: I think Ballhays was really Ballyhaise] I hope this helps one of you.
