I'm looking for info - and hopefully a contact - on the Roscommon Duignans. Margaret Duignan married a Martin O'Connor some time in the 20th century. Martin died in either 1960 or 1962. They had a son whose first name is either Michael or John (I've seen him listed as both. Probably Michael John), another son named Martin, and a daughter Maureen (I don't know if they had any other children). Michael/John married a Dolores Nolan.
Margaret was known as Maggie or Maggie Ellen. I believe she may have died earlier this year. She was my grandmother's sister-in-law. Anyone who may know this family, please contact me.
