Hello: I may be off a limb here but just in case:
Do any of these Boyle match up?
Edward Boyle b:Feb 4th, 1856 in Illinois, parents from Ireland
m: Mary - b: 1871 or 1872 in WI:.
they had a son James T Boyle, b: 1891 WI.
m: Rose M. Wolf
they had a son: James Joseph John Boyle.
But in my seaching: I found many James John Boyles (Ireland) going back back..back.
I am discontinueing my membership w/ ancestry.com this week (Feb 2007) and just happened to run across you.
So in case you want to contact: firstname.lastname@example.org
