RE: Cora Civils I found legible headstones for four Civils in Mountainview Cemetery, but not of Cora. However, her husband who died about seven years earlier is buried there and there are no other memorials nearby. I would suspect that she is buried in the same plot. Oddly, one of the other Civils stones mentions the husband's name but there is no stone for him. I don't know if there are cemetery records showing Cora, or perhaps records of an undertaker. Sorry I can't do more searching - seems it would be interesting.
RE: Cora Civils Not a problem for me. There are 15 or more such memorials in this cemetery that should not be there. I reported it as a problem, not found in a walk of the entire cemetery (which is quite small and ancient as you might see in the cemetery picture.) No need to send ne the death certificate - I've seen it and note that it was signed by a doctor from Altoona. If I find a marker or stone at Mountainview Cemetery I will post it and let you know in case you would still want a picture of it.
Cora Civils I have to check further. In the meantime I recommend that you transfer her memorial to Mountainview Cemetery in Mill Creek. It was the only active cemetery in Mill Creek at the time of her death.
RE: William Wolf The only other Wolfs I have found in St Paul's are Anna Wolfe, Harry Rey Wolf, Bess Gard Wolf, Cardit Wolf Ingebrigtsen and your William McCoy & Edith Wolf. I have photographed about 2/3 of the cemetery and have done the rows around William & Edith.
RE: Catherine Bortle I have John Van Tassel as having died in 1827. I got that from Daniel Van Tassel's Genealogy of the Van Tassel Family. I think the original entry on Find-a-Grave is from a transcription of the cemetery names by Minnie Cohen in 1939 where she notes that the date may be incorrect. All I know is that the headstone is very old and worn and virtually impossible to read. I was actually going back and forth about posting the the picture but John is my great great great grandfather and maybe I gave in a little because of that. You can kind of make out Van Tassel and the stone is just to the right of Catherine's. Let me know what you think.
