Charlotte Jones: 

Glassport holds the dubious distinction of being the location of the
crime for which the first woman in Allegheny county and the second in
Pennsylvania, was hanged. Charlotte Jones was convicted, along with
Henry Fife, of murdering her uncle and aunt, George Wilson and
Elizabeth McMasters, in 1857.   

The murder occured in an old log cabin located near what is now
Harrison street alongside of a run at the foot of the hill below the
present "Red Row."  Charlotte and Henry killed the old couple, brother
and sister, in order to get enough money with which to be married.

The story goes that Fife did the killing, slaying the man with a dirk
and beating the woman to death with a poker. They were hanged at
Pittsburgh February 12, 1858, Charlotte collapsing after kissing her
sweetheart, and Fife going stoically to his death with the words:
"Remember, gentlemen, I die game."

The murder occurred April 30, 1857. Charlotte is supposed to have
knocked at the door that night and gained entrance, after which she
summoned Fife by whistling.
