Does anybody have any information on my great-grandmother Anna Seebeck, who was born in Ontario, Canada in 1857. She was of German descent. She married Richard Jarvis and had many children, one of whom was Iva, who was my grandmother. She married Robert Porter. All of these grandparents lived in Markham, York in Ontario and are buried in the Box Grove United Church Cemetary. I think perhaps Anna's father's name might have been Willis and her mother's maiden name was Lehman (or similar spelling). Help!!
