Ruth B Sisk #91219397 West Laurel Hill Cemetery was incorporated in 1869. The person listed on this memorial and buried at West Laurel Hill Cemetery in Pennsylvania is not who you think she is. The person at WLH is a 1 year old child, born and died in Phila, buried with family members. See her death certificate now on her memorial.
I've sent some edits to the memorial manager on the Baker photo requests I filled for you in Schoolcraft Township Cemetery in Vicksburg, MI. They include a death date for Meta and name, dates and places for Herbert. (He was indeed the one listed as Baker b. 1891.)
The other Baker unknown one was a "MOTHER" marker. This is most likely Lydia as it is right next to Robert Baker's marker. I did not do any edits for her. I will leave that up to you.
your distant cousin I saw where you left a condolence note for Floyd Walter Gill ( 38065063 ) stating he was your distant cousin. I ran across a short newspaper clipping that told of his death in France and a photo of Floyd, thought you might be interested if you don't already have it.
