Oh, OK. Like I said previously, there is NO WAY for anybody on this Forum to tell you whether or not your cousin is entitled to receive a bonus and/or royalty payment without doing a heck of alot of research into your family tree, alot more than they care to. It is possible that your cousin does own a portion of what your great-great-grandfather had owned but that the oil-and-gas company leased you and your sister but not your cousin because they ran out of money, circumstances changed, they went out of business or were sold to another company with different priorities, or any of a whole lot of other reasons.
