About 1850, Paul Jones, the grandson of Gerrard, lived on a 27-acre estate called Ashland Hill, named after the Ashland Paper Mills. His home, located at 100 Lyle Avenue was evidently built about 1787. In 1856 the estate was sold to Se=tewart Lyle, who in 1901 sold it to a developer and the area became known as Belmont Heights.

Stewart Lyle's great-grandson still lives in Belmont Hills. When Art Lyle was growing up there was a pretty clear dividing line in West Manayunk. He recalls that there weren't even any Italian-Americans in the local volunteer fire department in the town until he was in junior high. "The English lived in Belmont Heights and the Italians lived in Ashland Heights," Lyle said. "The Italians tended to stay to themselves, as we did, and that's the way it was until we went to Lower Merion Junior High School," Lyle said. "Until then, most of the Italian kids went to St. Lucy's parish school, which had a branch on this side of the river. Once we got to junior high it was more important that we were all from West Manayunk than where our families originally came from."

Art Lyle also lived his life in Belmont Hills, except during WWII. He was an aircraft mechanic for the 2nd Aircraft Transportation Squadron, flying "the Hump" across the Himalayas into China. But that assignment took him to New Castle Air Base in Delaware, where he thought he had it made. "I was assigned so close to home that my girlfriend and I decided to get married," he said. She lived across the street from Lyle's house. "We went to New York City for a weekend honeymoon, and when I reported back to the unit on Tuesday I had orders to Florida and then to India," he said. That was April 1944. "I left several days later and didn't see my wife again until the day before Christmas, 1945." They too remained in West Manayunk living on what had been part of his great-grandfather's land. His wife, Ruth, passes away recently, but Lyle continues to live in the house and continues to be active in community activities.
