One possible answer would certainly be sons of ages 1, 5, and 7.  

	1+5+7 = 13
	1x5x7 = 35, a reasonable age for a friend of a father of a 7-year old

The weight of the eldest must be used to establish a reasonable upper bound
for the children's ages.  

I doubt this solution is unique (certainly it isn't if you expand the horizons
of "reasonable").  I can't see where any more constraints might come from, though.

Tim.
