Your ethnic composition?

[Plant City Rebel]

Purebred American Mutt, or in other words: English, Irish, Native American, German, Welsh, Dutch, French, and Scottish.

Verily, I can feel you on the variations.  My current stumbling block is my Maguire line  (my maiden name).  It seems that the males on my line only have 4 names, used alternately as first and middle combos. William, James, Patrick and Hugh.   The rest of the family lines have been relatively easy, with the exception of one ancestor who changed his name post 1865, we can't find him prior to the war with the name he enlisted under in any records.

Having brought out records, did any of the census records list a place of birth for either Bridget or Peter, we've broken several walls with those.  Of course they won't list city,  just state or country, but, that will help at least establish which course you need to run.
