Excuse me, the GF4 was a typo. My other posts referred to GF3.
However, if you read the original book....
Lucy Mancini went to Vegas. There was never any mention about her having a child of any sort, let alone one fronm Sonny C.
Nor was there any reference to that circumstance BEFORE she moved either.
Just remember......I ain't no band leader. Yeah, I heard that story...
Any research I have ever done supports that.......unless you have information sources of which I am unaware. If so....I would most certainly stand corrected.
