William BRISCOE m Sophia Mary MOUNTJOY, they are my 3rd GGrandparents.
Their daughter Elizabeth Ann BRISCOE b. 1856 m Joseph Thomas MOUNTJOY in 1878, they immigrated to New Zealand. (my 2nd GGrandparents)
Their daughter Cassandra MOUNTJOY b. 1888 m Ernest Alfred EYRES in 1914 Wellington NZL. (my GGrandparents)
Their only child Dudley Francis Briscoe EYRES is my Grandfather.
Although most of the information is correct there are a few variables.
I have traced my BRISCOE family to my 8th GGrandfather Edward BRISCOE 1651-1709 m Rebecca. They are from Kilkenny Tybroughney House.

My MOUNTJOY family have siblings/marriages back to my 5th GGrandparents.

Should you wish for clarity or further information I would be more than happy to share what I do have.
