My Rebecca J. Young, born abt. 1817 RI was married to Charles Gray LIncoln who died in 1846, then fairly soon thereafter the widow married James (A?) Cook. James Cook was born abt 1818 in NY. Census records include her son George Frederick Lincoln (sometimes listed as Cook) and Arthur Pettingill (also sometimes Cook). George later married Arthur's older sister Ella F. Pettingill. I am unable to find death records, burial info, or even better, an obituary for either Rebecca Young Lincoln Cook or her husband James Cook. They were living in Litchfield, Montgomery, Illinois in 1880 and I can't find them later than that. Have you seen them?
