Yes, my McDonnells are your family. Look on ancestry.com for my family tree Becker-Trout family tree. I've learned a lot about the McDonnell family since I posted your message.
I think Ann McDonnell is my grandmother's aunt. My grandmother is Geraldine Monica McDonnell b. 1910 in Winfred. SD who married Rudolph Carl Becker in South Dakota about 1932. Geraldine's father was Thomas Francis McDonnell.
Nice to "meet" you!
