I am wondering if we should look for Nels Edward Johnson as Edward Nels Johnson. This could maybe be him:
Denver, Denver, Colorado
Edward N Johnson 39 born about 1901 in Texas <--
Vivian Johnson 33 b abt 1907 Colorado
Gerald E Johnson 15 b abt 1925 Colorado
I hesitate to post this because I have found nothing to show this is Nels...
