Nice to hear from you!
I have no further info re: Poulson/Algonquin side of the family. I gather my great grandmother was born in Quebec but not sure of her origin. Native Canadian records are harder to find, it seems.
I had traced the Edwardson side back to the 1700's but Bergen is an interesting line to persue.
I live north of Toronto (about 4hrs) and previously lived in London Ontario. I was in England in March and pondered going to the Shetlands but.....sigh! It would be nice to see where some of my people came from.
