Am trying to find proof of parentage of Oliver Colegrove of Truxton, Cortland Co., NY marr. --- Laton. Colegrove Genealogy gives him as b. 1806, s/o Joseph Cole- grove of DeRuyter, Madison Co., NY, but his dau. Jane R. Colegrove was b 1819 in Cortland Co., marr. Elias Merritt there so Olivers' birth year is wrong. I need proof of Jane's parentage too as her death cert. has M Colgrov as her father.
