Thomas Ross was a 'Scotch Prisoner.' After the battle of Worcester, when Cromwell by his decisive victory over the Scots and Royalists became leader of England, he sent the prisoners he had taken to this country, selling them as indentured servants to the colonists. They were permitted to work out the terms of sale and became some of the best of the colonists of that time (1651). Thomas Ross arrived 11 Nov. 1651, on the 'John and Sarah' of London, Capt. John Green. (Suffolk Deeds, 1:6.) (The printed copy erroneously gives the name as 'Jonas' instead of 'Thomas.') In 1656, he was a servant to Edward Winship of Cambridge; in 1658-59 'he had liberty to mow the grass in the swamp anent the north end of Spy Pond.' He became a substantial citizen, leaving at his death an estate of over £222. After his marriage he lived for a few years more in Cambridge, removing about 1670, to Billerica. …
