I need help with finding dates for three children who died around 1920's and 1930's? I found tombstones in Pine Hill Cemetery but they had no birthdates, or death dates. The names are: Doyle Clifford Stahl, Rubin Evert Stahl, and Wilma Trevlene Stahl. Not sure where to find this information since the dates are not on tombstones. Thank you!
