Emily Anna Krc, as you already know, was my grandmother. Her husband, Rudolph James Staffa, was married first to Emily's sister, Bessie, who died from childbirth. RJ then married Emily, as was a common practice in those times because there was a baby that needed a mother, the families knew each other and life was not as free to pick and choose a wife or husband as life allows today.
If you will email me at firstname.lastname@example.org I will happily forward the dates you are requesting for those that have passed on. The living still deserve their privacy.
