I am new at this posting business. I am responding to several posts at once. Is that okay?
1. Research: more digging has uncovered: Mary Ann died 09-05-1884, Osakis, Douglas Co, Minnesota, USA. I agree that the birth date in 1830 is doubtful. The 1880 Census has a Mary A. van Schoonhoven born in Ireland in 1827. It is also possible that the marriage date is incorrect; their first son was born in 1854.
I have a picture of John B. and Mary Ann (Pyner) van Schoonhoven (undated), which I have posted on Wikitree.org (
http://www.wikitree.com/wiki/Van_Schoonhoven-34) if anyone wants to see it. I can't date it accurately, but I understand the photography started to catch on in New York in the 1840s?? I don't know how long it would take for photography to get to Minnesota, which was largely rural and forested land.
2. Birney/Bernie parents: unfortunately, I do not have Susan Birney/Bernie's parents' names. One unverified source calls him "Sir" ___ Bernie, b. 1764.

3. Yes, I always liked it. It would be even more enchanting if there proved to be a touch of truth to the story.
