Yes, it appears that Marlene's mother is still living per Marlene's obituary. I am unfortunately not familiar with the family, just the sad situation surrounding the untimely deaths. The obituary states that Gene is her father, unless you have reason to doubt he is. Your best bet is to obtain a birth and/or death certificate for Marlene and these documents will state the names of her parents. This can be done online or by mail since you live out of state. There are fees involved and all the information can be found here: https://www.odh.ohio.gov/vs. I hope this helps in some way!
RE: Gene R. Perkins Hi Anne, Yes, I am familiar with the sad situation. A good friend of the family was best friends with Marlene and was devastated by her death. Just to clarify, was your question whether Marlene was the daughter of Gene? It is all such tragic circumstances and I'm very sorry for the loss of your family members.
Kraus and Balling at Holy Sep I posted photos to the memorials for Frank and Ottilie Kraus and John Balling. I just happened to take them when taking photos for other requests and then saw that you had some interest in them.
RE: Helen Morrisey Hammond Hints are leading to St. Columba's Cemetery, but conclusive evidence has yet to be found. According to "The Newport Daily News" (local newspaper, John P. Hammond, Director of Sanitation, was one of the delegates for the funeral of the foreman of the sanitation department in 1961, so John P. Hammond was still in the Newport area at that time. Family Search.org (citing billions of graves) has John P. Hammond born 1900 as being buried in St. Columba's Cemetery, however there is no death date listed, which makes this information suspect. It is possible that John had his name & birth year engraved on the gravestone in St. Columba's prior to his death with the intention of being buried there at the time of death. I ran both him and Helen through Billions of graves index and they both did show 1 relationship, so it is possible they were interred together. If you find evidence substantiating his burial I would be most interested.
