No I haven't put her into Wikitree yet. I'm still uncertain about her mother's death also.
I recently was handed management of Melva (Shirley's mother) in Find A Grave (the previous manager didn't have any info). The cemetery doesn't have their own website with a list of interments and there is no picture of a headstone, so her death is suspect.
I also find references to a Melva L. McConkey b1912 that died in 2002 in California but can't get full info on her. The name Melva isn't common - so I'm actually wondering if there is a grave for Melva in that cemetery.
Anyway, that is a long answer - no profile yet as I don't have a lot of info about that side of the family.
Update: I added Melva and Shirley 2/9/18 1:26pm Eastern
