A lot of things have been written about Col John Gibson. Some are true and some are not. Even the Horn Papers of the early History of Pittsburgh from 1700 to 1775 has his fathers Bio.
First what is true. His family is buried at Allegheny Cemetery in Sec 2 lots 1&2. They contain Col John Gibson and his daughter Ann and her husband George Wallace.
There is also a Mrs Mary Thompson, Jane Coston and Arabella W Beltzhovre.
Col Gibson was married to Chief Logan's sister. She was killed in the Yellow Creek incident touching off the Dunmore War.
The names involved in the incident are Gibson Logan Greathouse Myers and Crawford.
I am trying to piece together a family tree.
This may not be true if it were not for some DAR records.
So far I have now John Gibson from England moved to Lancaster PA around 1725 and was married to Anne St Clair who was the great aunt of General Arthur St Clair. Their son George Gibson married Elizabeth DaVinci from France and moved to Pittsburgh. Then their son was Col John Gibson married to Chief Logan's sister. Col Gibson is buried in Sec 2 lot 1&2 at Allegheny Cemetery with his daughter Ann Gibson and her husband George Wallace.
Then General Arthur St Clair is buried at Greensburg PA in the St Clair cemetery. In 1913 he was moved to a better location in the cemetery and a monument was placed over his grave. The Heinz History Center has the records of these activities and monument placement in 1913.
Then the Chief Logan Monument is at Fort Hill Cemetery in Auburn NY. I have been to both cemeteries photographing everyone around Col John Gibson and Chief Logan.
Some of the Gibson family indicate George Gibson, a nephew of Col John Gibson, was on the Lewis and Clark Expedition. For sure about 40 ft from Col Gibson is the monument to William Croghan who was a near relative to the Clarks of William Clark. William Croghan Sr was married to Lucy Clark the sister of William Clark of Lewis and Clark Expedition out of Pittsburgh in 1803.
