my grandfathers's uncle, (both "frank") settled in or around Racine from in or around Cosenza about that time.
the most prominent member of that branch was his 1/2 brother, James (Jim), a former member of "Lafiette Esquadrille", Cop, and Dep. Sherriff during the 20's and 30's when the area was a "bedroom community" for the Chi mob, who he had several (fatal) run ins with. He was also an active Vet later in life who died in his ninties around 1975.
might be helpful to trace that side of the Greco's in Kenoshia/Racine area. (jim didn't have any kids)/
