It is well settled that once a party pleads and traces his root of title in an action involving title to land to a particular person or source, and this averment, as in the present case, is disputed or challenged, that party, to succeed, as a plaintiff in the suit must not only establish his own title to such land, he must also satisfy the court on the validity of the title of that particular person or source from whom he claims to have derived his title. See Mogaji v. Cadbury Nigeria Ltd. (1985) 7 SC 59, (1985) 2 NWLR (pt.7) 393 at 431; Elias v. Omo-Bare (1982) 5 SC 25 at 37 – 38.
