I can not find my Irish father's ancestors at all. Potato famine of course. Not a one although second cousins wrote and said Bridget Quinn is your gggm. Someone else wrote and said Mary Fitzgerald is your gggm. But I think she was a generation before. Mother's family paternal side was very colonial virginia with all known abuses of the day. Very easy to trace.I could find 200 new ones a day. Descended..if I am correct..from all sorts of english, norwegian, scottish royalty. lots of norman. lots of stewarts. the usual sinclairs. ancient welsh. mother's maternal was dutch who intermarried with engish/early settlers of usa. People always guess I am Norwegian, which totally confuses me because I don't think I do at all..maybe Cornish...but my crone like hair is growing out and when I braid it I can see Norwegian. I don't see a speck of Irish although I am half. We have a lot of prejudice in the US...but not just the known about ones...we are very very prejudiced, and it is socially blessed, against southerners if we are northerners or from other countries.
