Hello, I am looking for any connection to Mary Ellen Mulrennen from Roscommon with relatives in Mayo and Sligo too. I remember my grandmother mentioning a Dalton, but as to what context, I don't know. Could Mary be one of her children? Mary Ellen was born about l866, as she was listed as 44yrs, in the l910 PA Census. My grandmother, Anna (Anastacia) DeWitt, is one of Mary's (she went only by 'Mary') five children born in US after Mary Ellen married Charles Henry DeWitt. Anna's siblings are Maize (spel?), Joe, Isabela,and Clara, all born in NJ. Thankyou for any info, you might have.
