On p.30 of the rulebook are the rules for voluntary transfer of bloodline. If
the child's bloodline is stronger, he only gains 1 point. Although it doesn't
state so, I would assume that if the father's line is stronger, it would
replace the child's current line. Bloodline investiture is a special form of
the normal investiture ceremony which involves the transfer of titles,
holdings, and regency - not blood.
