For your cousin to kill his curiousity regarding the number of women and
children this Lou Salvador sired, the person most indicative to give him
the closest answer to the truth would be a Salvador descendant. His
junior (Lou Salvador Jr) is living somewhere in Las Vegas and it will
not be difficult to trace him thru the Filipino community there. But if
rumors were to be believed, he fathered 121 children and not 103 as
printed, and it pretty much looks like he himself could not recall all
of them save the ones who were all within the Metro Manila area and who
all know one another, because acc. to the grapevine, he had a big board
like this boards where you post on cork, and everytime he was told of
the birth of a girl he hang up a bracelet, and if it was a boy he hang
up a watch, so all he did was to count the pieces on display and that
gave him a good idea of his number of kids. But for more exciting
tidbits, you can probably do more explorations on your own and see how
well you will fair..
