The following is a portion of an E-mail received from a lady following a request for information I had on the location of the grave in the cemetery. She also mentioned in other correspondence that Moses may have first come to the area with the Braddock forces. That would need researched further:

I will tell you what I know of Mr. Stewart or Stuart. First off I believe the headstone was misspelled and once it is as they say, " in stone" it was to late to correct and left as is. In my resaerch, in the early years it was spelled Stuart then later on near the time of his death it was spelled Stewart. His sons Andrew and Moses show up as Stewart.
Issabella-----Lowers. Issabella
[maiden name unknown] married first Andrew Lowers and had three children to him. Andrew Lowers who also joint owned land in the Derry settlement with his brother Robert Lowers. Andrew however died in Cumberland CO. Issabellas daughter, my g-g-g-g-grandmother Mary Lowers married Thomas Wilkins and was very early in the Derry settlement, 1768. The Wilkins and the Stewarts lived in the northern part of the county along with John Wilkins, brother of Thomas. They all lived east of Blairsville and north of the Conemaugh. If you are familiar with the area, Rt 22 goes through my Thomas Wilkins place. Their is a golf course where his farm was. Then Stewarts was north of Thomas Wilkins place.
Back to Moses. Moses and my Issabella were marrried in 1760 in York, York CO Pa. I found the marriage record of this in LDS Records. On the records it says that she is the widow of Andrew Lowers.
I dont know who was over in Derry first, but I think it may have been Moses. I have the warrent for my Thomas Wilkins first parcel and it lists Moses as one of his neighbors. I also find that Moses and Issabella had at least two sons, Andrew and Moses Jr. Those two migrated to Ohio and died there.
I wonder if Moses had been married before he married my ancestor. He was very old when he married her and also joined the Revolutionary war as a member of the Westmoreland CO Militia
