I have just binge watched both series of Agent Carter with C, and it occurs to me that Joseph Manfredi and Silvio Manfredi (the Spiderman villian Silvermane) are probably related. Given Silvermane's age in the comic they could well be brothers - two branches of the family setting up buisness on either coast after they arrived from Italy.
Curiously, nobody on AO3 seems to have come to this conclusion; indeed the only tag for Joseph that I can find is in a slash pairing with Howard Stark.
I feel the need to write something to
exploit explore this relationship.
