Were your four grandparents from Roscommon? If so, you may be interested to help with a geo-specific DNA project.
Dr Turi King from the Department of Genetics/School of Historical Studies at University of Leicester explains:
“I’m working with Dr Cathy Swift, the Director of Irish Studies at Mary Immaculate College, University of Limerick, on a small study of surnames in Ireland linked with DNA.
“As part of this study, we're hoping to collect men with all four grandparents born in Co Roscommon, ideally (but not essentially) with Roscommon surnames.
“Those taking part would have a chance to learn about their genetic history for free. “
If you fit the bill and would like to know more, contact Dr King.
