All my family research was done over 15 years ago at the Archives when I lived in Toronto.
I have many copies of birth and death certificates for Robert Whitten's descendants.
I have been living in Quebec now for the past 10 years.
You mentioned that your father has been to Armagh and knows which parish the Whittens are from. Since my great grandmother was a Whitten, I would really appreciate if you cold tell me sometime which parish this is. I have been trying desperately to figure out exactly where the Whittens are from in Armagh.
My Hewitts are from the parish of Kilmore and their church is located in the hamlet of Kilmore which is about 2 kilometres northwest of Portadown.http://en.wikipedia.org/wiki/Kilmore,_County_Armagh
