Hi David,
John Titus and parents were from a different family which has been referred to on this board multiple times under Corkill of Ballagorry Mooar, Maughold.
John Corkill who married Mary Ann Brew was a miner who moved around to different parishes, and his son (always known as) Titus ended up in the USA.
Which is not to say that the Ancestry trees are correct. The Corkill ones I have seen have often had numerous errors copied from each other.
