The 1910 census says that Ellen has had 7 children, 6 of whom are still alive.
Marriage was witnessed by Patrick Moriarty (Daniel's brother) and Mary Shea (Ellen's sister?).
The state record of the marriage dates it to 20 Apr 1897 while the church dates it 21 Apr 1897. Both record the record on 22 Apr 1897. I presume that 21 Apr is the marriage and 20 Apr is the license date.
In the 1910 Census, she is listed as emigrating in 1894 and has had 7 children, six of which are still alive.
