I don't know Solomon's dates; however, I did find a US record for Solomon Orser (also Isaac Orser, Gabriel and and Arthur Orser)in the source "Loyalists in the American Revolution, The Old United Empire Loyalists List, Appendix B, Page 232"
Solomon is listed, residence Kingston under last column it notes, "Loyalist from New York- A. McL.-M. Collins' Book.P.L. 1786" Arthur is listed as Kingston, Gabriel is listed as M. District; Isaac is listed as do meaning M. District as above.There is also a William Orser listed as Kingston under residence.Would this be the Solomon of whom you mentioned?What is Sarah's wife of Solomon's name?
If they were loyalists and fought for the King in the Revolution, then they were entitled to land as comensation in Canada.I don't have access to the Canadian census to check these out. Since they are all listed together, one may assume they were somehow related.
Sarah Jane Emes and Edmund Martindale came into Michigan and are buried there.Have you any idea where Christiana Orser Emes is buried?You noted she died on her family farm.Do you know where that was?
I too live in Michigan presently.The Mormon center is fairly far from here and is poorly equiped.They have no copier as they can't afford the toner for it!People are willing to pay for the copies of records; but they don't buy toner with their proceeds.I can drive into Detroit Library (have done so on numerous occasions); but the roads are all torn up and I am unfamiliar with all the alternative routes (most of which are also under construction).
