Clarence "Scotty" Scott says his sister Lucretia came to live at the Elwyn Institute in 1997 after her mother passed away.
"She really grew into being a real person," Clarence explained.
Lucretia's mother had taken care of her since a fall she took when she was just a baby, which left her physically and mentally challenged.
The brothers have watched Lucretia flourish at the Elwyn Institute.
"She's just more open, she expresses herself really good. Just a night and day difference," said Douglas Scott.
"Scotty" said, "It is probably the most important foundation there is, as far as they're concerned."
There are eight Scott children, and three of them became NFL football players.
"Scotty", the youngest boy, played for the New England Patriots in 1969.
Arthur, the second oldest, was among the first group of players in the American Football League when it was being formed in the early 1960's. He became a New York Jet when the name changed.
Douglas, the third oldest, didn't play football, but he came today because his brother Lewis could not attend.
Lewis was a Denver Bronco in the mid sixties.
The family presented Elwyn's President Dr. Sandra Cornelius with a $3,000 dollar check today because they wanted to show their love for their sister and for the Institute.
"We want to give something back to show that we appreciate what they've done for her and that's our small way of showing it," said Arthur Scott.
"We will be able to continue to refurbish the building, adding entertainment and social events to the residents lives," said Dr. Cornelius.
The brothers say their sister has been transformed by the 'can do' attitude of the Elwyn staff.
Dr. Cornelius added, "It isn't that you can't do this or can't do that. We say, 'Okay, let's give it a try.' And of course she has many more friends now."
Brother "Scotty" added, "The next thing I knew she had a boyfriend and I knew it was serious because she was bossing him around."
