familytreedude on Family Tree Circles

My family tree starts with Richard Brown 1823 Ireland married to Bridget Tierney 1837 Ireland. Allen is born and down the line with documents to prove.

1881 Canadian Census has George Browne married to Bridget same children only the "e" is now present.

Richards parents are listed as Allen Brown and Mary Wiseman. Richard being the only child.
When you change Allen`s last name to Browne you find him in Ireland married to Mary Wiseman only then 11 children are listed and Richards birthdate changes to 1818.

Also with in the family tree are documents about a Rev Richard Brown 1643 - 1712. Why these are here I do not know. I have researched and come up with a John Garde Browne 1818-1883.
Richard Walter Harding Browne 1841-1921 son of Richard c1805.
