abennett on Family Tree Circles

Here is a brief synopsys of the Cornwall Bennett's I am looking for:

Richard Bennett - born St Columb Major about 1818 - he died between 1881 and 1891
Richard is my Great Great Grandfather
he was married to Mary Ann(e) Stephens - I am unsure if this is his 1st or 2nd marriage
I believe they had 3 children; Herbert, William, Martha
Willam Henry lived in Duloe about 1908-1912
in 1912 he immigrated to Canada with his wife Sarah Ann(e) Stacey and their 2 children; William James & Violet
William James Bennett married Elizabeth Victoria Bowden (immigrated from Scotland) in Montreal Canada, they had 6 sons, who are all currently living in Canada, one of which is my father Edward Bruce Bennett.
