I have just begun to pick up a very cold trail, and I am not sure if this relates to the original posting by Bob Sharpe.
My great grandfather was August Kinsvater, and was married to Amelia Lehmann. They moved to the New Liskeard area in northern Ontario around 1902 from somewhere in USA. Family legends that have not been proven are that their early children, Ann, Ernest and Robert stayed behind in the USA. Children Rose, Pauline and John who were born in USA and moved with them to Ontario. Subsequently Minnie, Louise, Teresa, Jean and August were born in Ontario.
I am not sure if this is the same August Kinsvater from Burtenbach Germany, but in other web searches that I have done, he is the only August Kinsvater that I have found, and his wife is shown as Louise Lehmann. Is it possible that her full name was Amelia Louise Lehmann?
I would be interested in sharing any information that might confirm a linkage or otherwise with any information that you might have.
