After finding "Kate" on an 1860 census record, aged 20, with her older brother George Gates, I'm questioning whether this grave memorial is actually Catherine, "dau of Jacob and Jennie", or if the information on the memorial concerning her date of birth is incorrect. Photo of grave marker was requested 30 Jan 2013.
The grave marker request was inconclusive. The marker is broken and unreadable, but it is within proximity of Jacob Gates. Census records are also being next to useless in proving out this issue.
