Looking for info. on the Cornelius & Isabella Mars family. He was a Methodist preacher. They res. Seneca, Ontario Co., NY, then Lewiston, Niagara Co., NY. Two daughters that I know of: Jane Mars b. 1802 NY mar. Elijah Carman and d. 1870 in MI. Sarah Mars b. 1807 NY mar. John Beamer, d. 1862 in MI. Both daughters and their families moved to Genesee Co., MI in 1830s. Cornelius & Isabella followed and are buried there. I have Elizabeth who married Peter McGregor, supposedly maiden name was Mars, wondering if she is another daughter. She was b. ca 1800-1805 in Montgomery Co., NY, res. in York, Livingston Co., NY and Pendleton, Niagara Co., NY after marriage. Died after 1870- where?
