Ok, I kind of figured this would be his family based on the information I have received from relatives over the years, they did seem like a really good match. :) One thing I wonder is, since they were both in their 40s when they got married, were John and Lois married to other people previously?
Ok, so the trick with Ancestry trees, as always, is confirming the info we find. :)
Kathryn's 2007 obit states that her siblings "Wally, Jack, Henry, Arnie, Sally (Cordes), and Mary (Mahnke)" died before her. I'm assuming that Arnie is Orlan and that Sally is Marcella? If so, she was the last one still alive. Also surviving are Henry's wife Ruth and Arnie's wife Sally. No burial location for her. No first name of spouse listed, so possibly divorced.
Henry's obit was a bit more useful, and it did lead me to a memorial: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=68...
which also has links to the parents as well as Wallace and Orman.
Bernard makes for another unexpected connection to Olmsted county MN! His memorial lists the dates for all of his children, but of course I still want to confirm.
No luck finding an obit or memorial for Mary Mahnke or Marcella Cordes to confirm their info.
Regarding the spouses, I have found memorials for Ruth Johnson and Patricia Thompson for Wallace Gorman, Ruth Cooper for Henry Gorman, and Sally Moore (tree says Triske) for Orlan Gorman.
This memorial matches the dates from the tree for James Harrington: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=14...
and for Aloha Hammack Gorman: http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=71...
so hopefully we can verify that these are the right people. No luck finding anything for those dates for Stanley Cordes, Fred Bower, or William Mahnke.
