Patrick and Mary Cannon were listed in the 1850 Pittsfield census. My great-grandfather, Thomas, was born in 1852 and possibly a brother, John, in 1854. I am attempting to link these two people to Patrick and Mary Cannon. If SKS would do a look-up for me for these years, 1855 & 1860 if possible, it would be greatly appreciated. Willing to help anyone researching in Minnesota. Regards. Jim Cannon
