Interesting Newspaper article about Donald's conviction.
Berkeley Daily Gazette
Wednesday, August 3, 1910, Berkeley, California

I had to cut the article into 4 parts from page 1 and 2.

First two (Moore 1 and Moore 2) are from page 1. Next two are from page 2.

Second page indicates Moore returned from Salt Lake.
I found this marriage that is a good possibility:
Stated his year of birth is 1889 aged 21yrs.
If the legal marry age was 21, he may have had to lie on the application.
