I have not seen the 1850 & 1860 census records before as I have home access thru my library to 1880, 1900 & 1920. this all helps round out some info that I already have thru the family.I plan to go to the Williamsburg Library in the coming days to dig a little deeper.
Thru the 1880 census I found ythat kate was born in CT. I had heard some time back that "The family" came into the USA from Ireland thru (I thought)Bridgeport,CT but I wasn't certain just which family members that applied to so your info is helpful.
I e-mailed firstname.lastname@example.org last night and it bounced back "unknown" immediately. His interest was posted back in 2003-2005 so I guess he has moved on to a new e-mail address as I have since that time.
