Are you Irish?

Happy Saint Patty`s Day!
Yes,I am partly Irish.I`ve been looking into my roots lately.The new show on TV that has celebs finding their roots prompted me.I come up in roadblocks on my father`s side.On my mother`s side,my grandfather was Uhler Haggerty.Unfortunately,the only memories of him are scary.He was a mean man,drunk alot of the time.He ran a dairy farm,was good around the animals,but when we would visit,he drank alot & was unhappy.This picture of him is the only time I saw him smile.The woman he is pictured with is Margaret.She was his mistress whom he moved into the farmhouse while my grandmother was still living there.My grandmother & he had 5 girls.When Margaret moved in,my grandmother had no choise but to leave.{If she had been me,I`d have stayed!}She left my mother & her 4 sisters with him.I don`t know the why`s of it all,I do know my grandmother ,Ruth Loller,had RA like me.Maybe she couldn`t keep up with the chores,I don`t know.I do know when she left,she had to get a job to support herself & she eventually moved on.
Margaret moved on too,she did not stay with my grandfather.The girls suffered & worked hard on the farm.They all graduated from school,but 2 of them ended up with mental illnesses,one being my mother,& the oldest is an alcholic.I have ideas of what may have happened,will post more of the story as I find out the details.
