Re: Patrick Featherston(e)

Do you know what part of Ireland Patrick is from? My grgrgrandfather was William Fetherston born circa 1838, Co. Roscommon. His father's name was Darby and he had a sister named Letitia. I haven't found his mother or other siblings, yet. Fetherston is not a common surname in Ireland--they are all no doubt connected.
