I have some information on Patrick Powers, but only the 1920 Federal Census info for Patrick and Anna B. Since your wife is a relative, I'd be happy to give you access to my family tree on Ancestry.com so that you can see if there is anything you're interested in. I restrict access to relatives because there is a lot of information on living persons. If you send me your regular email address (to my regular email address) I'll give you access to the tree. Perhaps you can fill some gaps or make some corrections in my data.
My regular email address is firstname.lastname@example.org.
