If Jacob & Rebecca were married in 1732, they cannot possibly be Submit's parents, as she would have been born about 1800, and no earlier than 1780. You are likely missing a generation or two in between.

I did find this marriage:

#08785/89 (Durham Co.) Moses Locke, aged 65, b. Canada, of Michigan US, widower, farmer, son of Thos. & Submit, married Elizabeth Pierce, aged 52, b. Canada, of Bowmanville, widow, daughter of Jesse & Clarissa Vancamp; witnesses: Clara & J.H. McClung of Bowmanville; 5 March 1889 at Bowmanville; both parties Methodist

From the 1883 History of St. Clair, Michigan:

Moses LOCKE, farmer, Section 4, P.O. Jeddo, is a native of Canada, and was born August 5, 1823; his boyhood was spent there. After reaching manhood he came to this county in 1845, and he worked at lumbering on Black River until the spring of 1847, then bought land and settled opposite where he now lives. It was all a wilderness, nothing was opened; he built a log house and began clearing his land, making his farm during the summer and lumbering winters, and since then, over one third of century, has resided here; he owns his farm; is engaged in manufacturing molasses, and can also make sugar, and was the fist to engage in the business here; he has held school offices many years; is now Justice of the Peace and member of the Town Board. In 1846, he married Miss D. VANCAMP, a native of Canada. They have one son-George. pg. 752 Grant Twp
