Found the Damon C. & Virginia (Mary) Rollison family on the 1920 Censis for Pennsylvania, PHILADELPHIA, Roll 1637 Book 1, Page 25a. There marriage was listed in the info. I provided. The wife was listed as Mary. V. but was listed as Virginia M. on the Census. I hope this helps someone. By the way; his mother was still living at 80 years in 1920, her name was Louisa J. Rollison.
