I just came across your message. William and Adeline Martel were my great-grandparents. My grandfather was one of their younger sons, Augustus who was born in 1891 after they emigrated to Ogdensburg, NY. Many of the Seymour siblings are buried in Notre Dame and St. Mary's Cemetery in in Ogdensburg.
Your message is very old, so I'm wondering if you've located any information on William and Adeline?
