William L. McKee petitioned, through his mother Elizabeth McKee, for a guardian.The Allegheny County Orphans Court appointed John McKee as his guardian on 30 April 1855 (vol. 12, p. 490).
Robert McKee was appointed administrator of the estate of William's father, James, in 1854.
The question is which Robert and John McKee were likely to live closest to Jefferson Township or the Mifflin United Presbyterian Church, where James was buried.
I think Robert was Robert McKee (1806-1882), who lived in Baldwin Township in 1850, in Snowden Township in 1860, and then moved to Hancock County, Ohio, where he lived in 1870.His son was John L. McKee (1834-1920), who also later went to Ohio, and I think this was probably the John who was appointed guardian in 1855.
Although I'm not 100% sure, I think Robert's father was John McKee, born 1776-1780, living in St. Clair Twp., Allegheny Co., PA, in 1830.His wife was named Elizabeth.In 1829, there are deeds where he sells land to his brothers.He sold land to Robert and Samuel McKee, who I think were his sons.
John was the son of Robert McKee, who died in 1828 in St. Clair Twp.He married Elizabeth, daughter of Oliver Miller.He had a number of children.Robert was undoubtedly the brother of my ancestor, Gavin/Guian McKee (1750/1-1827), who left the Peter's Creek vicinity for Fleming County, Kentucky, in 1789.They were definitely related to the McKeesport McKees.Gyon sold his land warrant in 1789 to John McKee, so he personally knew him.According to oral tradition in my family, the McKeesport founder was related.
There's a bit of work on this that remains to be done, mostly concerning John McKee and what happened to him after the 1830 census and the 1829 deeds.However, it seems reasonable to assume that James McKee was his son.
