Hi Eric,

When I did a search on the MN Hist Soc death index http://people.mnhs.org/dci/
using the mothers maiden name I found this:

MARIIN, CHARLOTTE LOUISE
Date of Birth: 09 Sep 1917
Place of Birth: MINNESOTA
Mother Maiden Name: RUSTAD
certid# 1998-MN-009827
Date of Death: 27 Apr 1998
County of Death: AITKIN

the other 2 were not listed.

If you are a subscriber to Ancesty you can look at the birth index.

It appears Charlotte Louise Cheney was married several time she had 1 child with James C. Hannah, in 1946 and 2 children with Russel E. Lee on in 1937 & one in 1939

Minnesota Marriage Collection
Name: Charlotte L Hannah
Spouse: Waino E Martin
Marriage Date: 20 Jun 1964

Alvina May Cheney married Donald D. Lowery and had a child in 1951

***** both Charlotte and Alvina were living in Freeborn, MN at some point.*****

There are several Betty Cheney's listed, but only one had children in Aitkin Co: Betty Elmire Cheney who married William T. Lyman and had a child in 1939 and another 1941

Not related, but I hope this helps your search
