I am sure that the Guglielmetti line that you are looking for is tied in with the same Guglielmetti line that I am researching. My wife is Maria Gugliemetti and her father is John J. Gugliemetti (not a typo error). His father was Battisto Guglielmetti. Battisto's brother was George Gugliemetti; he also had a sister (possibly Domenica). George's original name may have been Giuseppi. He changed the family name to Williams (Guglielmi in latin is William, or Guglielmo in Italian). Perhaps the reason you are having a hard time tracing some of these connections is because of the name change. George had several children. They were Benjamin (called Barnie), George (called Georgy), Silvio, and Louis. (Georgy may have been at our wedding, I don't remember. My wife still remembers his wedding present - a beautiful pair of sterling candlesticks that we have to this day. )
They were indeed in the amusement park business around New England including Riverside Park in Agawam, Mass, Canoby Lake in New Hampshire, and Roger Williams Park in Providence, RI. Barnie was the first owner of the PTC#44 carousel from the Philadelphia Tobbogan Company. He sold it to John Araldi, who then sold it to John Gugliemetti, Maria's father, in the 1920's. John kept the carousel at Riverside Park during the 20's up to about 1938 when he was forced to sell it because of the depression. He sold it to his first cousin Georgy WIlliams for $3000. His mother told him to burn it rather than sell it at such a loss, but since George was family, he decided to sell it. George moved the carousel to Roger Williams Park until it was sold in 1973 to King's Dominion Park near Williamsburg Virginia, where it is today (and probably worth millions). Maria remembers all the free rides that she and the family received whenever they visited Roger Williams Park. The memories are somewhat bittersweet.
I don't have too much on George's side of the family. John Gugliemetti, George and Barnie's first cousin, is now 103 and living with us here in San Jose, CA.. Even at 103 John still has a soft spot for carousels. He does not remember too much about George's family.
I can share more about the Guglielmetti - Mazzocchi connections if you contact me directly at email@example.com
. I would be very much interested in learning anything you could share with us also. I'm always interested in filling in blank spots in the family tree.
