Thanks to familysearch.org, I have an extract of the marriage certificate of Kristian Danielsen and Mary E. Reynolds, listing her parents' names. [The marriage date does match the index entry I'd found online some time ago: 30 Oct 1898, Bronx NY.] Mary's father was NOT John Reynolds [per her death certificate] - it was Edward Reynolds. Her mother's name was Mary Dolan [or Dulan], daughter of Patrick and Mary Dolan [Dulan]. Thus Mary Reynolds Danielsen named her second son, Edward, for her father.
I've found a few census entries for these families. Patrick Dolan emigrated from Ireland between 1840-1845, and resided Westchester, New York from at least 1850 through 1870. He and his wife Mary had 3 daughters, the older two born Ireland, the youngest, Mary Dolan, born New York. His occupation was always listed as "laborer" in the federal censuses, but he also showed assets of $1000 to $1500. He died probably between 1870-1880.
Patrick's daughter Mary Dolan married Edward Reynolds about 1868-1870; they lived with her father [who was probably widowed] in Westchester as of the 1870 census. Edward Reynolds was born in Ireland; nothing has been found on his family or immigration as of yet. At 1880 he and Mary had 3 sons [another son having died young] and a daughter, Mary Reynolds who would grow up to marry Kristian Danielsen. Cannot locate Edward Reynolds or his wife Mary in the 1900 census; they may have been deceased by then. [I have found possible entries for two of their sons in 1900.]
This also answers the question as to where Mary Reynolds and Kristian Danielsen met: he worked in Westchester as a waiter as of the early 1890's, and she was born and raised in Westchester. Their 1898 marriage took place in the Bronx although a 1903 City directory showed their residence still in Westchester. It's possible the nearest courthouse was in the Bronx.
Again - thank you familysearch.org !
P.S. The Sullivan connection remains up in the air, as Mary Reynolds had no sisters!
