Per my contact via 23 and Me with a Reynolds descendant, Kristian Danielsen's wife Mary Reynolds probably worked with her mother, who ran a boarding house for the workers on an estate in the Bronx [or Westchester?] area. I'll have to review our emails, but I believe Mary's father was a foreman on the estate. With family history saying Kristian and Mary met and/or both worked on an estate, it isn't a huge leap to see Kristian working and/or boarding at this place, putting a lot more truth to that item of family history.
On Kristian's naturalization papers he said he resided Westchester, and his occupation was a waiter. In later years, after marriage, he was a butcher. I wonder if the estate was where he learned his trade?
