Here is my Winterson Tree: http://trees.ancestry.com/tree/19835843/family?cfpid=2001747...
It looks like Frank Francis Winterson's father was Owen Winterson/Rose Maguire. Owen Sr. was born in Doon, however, his father, Owen, b. 1796, was born in Cavan.
The last I have of Ellen Rose is she came back from Ireland to Boston on 14 Oct 1928. she must have married shortly after that, because she doesn't show up in the 1930 census.
Here is the e-mail of Rick Winterson who descends from the Boston Wintersons. He might have some information: firstname.lastname@example.org
