This is pure conjecture, but I am wondering if Lucy Hogg (my husband's 8th Great Grandmother) is a direct descendant of one of the Scot prisoners transferred to the New World (and sold on arrival), on the ship, The Unity, in 1650. The time frame would probably work.
“The final mystery is oneself. When one has weighed the sun in the balance, and measured the steps of the moon, and mapped out the seven heavens star by star, there still remains oneself. Who can calculate the orbit of his own soul?” ― Oscar Wilde, De Profundis
