I went to the Wyoming Room today in the Sheridan Fulmer Library and did not find any death records or birth records, nor any Gird's in the cemetery records. I also looked in the marriage licenses through 1929 and didn't find any Gird's that were married from 1910 through 1929.
What I did find in the City Directories was:
1908 - John was a teamster, he lived at W.7th at S.W. corner
of Spaulding St.
1910 - John was a stableman for E.N. Campbell and lived
at 205 E. Brundage
1912-1913 John was a driver for Keystone Barn and lived at
333 N. Jefferson
1915 - John was a teamster and lived at 164 W. Brundage
I did not find any other name under Gird such as wife or children.
then in 1916-1917
I find Anna living at 25 S. Scott st. no occupation and no other Gird's named.
After 1917 I didn't find any Gird's at all.
Sorry I didn't find more.
