Major George Colclough, Ursula's third husband, was a burgess in 1658. After his death Ursula Bish Thompson-Mottrom-Colclough married Colonel Isaac Allerton. Even after she had married this fourth time she continued to have trouble in settling Colonel Mottrom's estate, because of the "ambiguities" of his will. Colonel and Mrs. Allerton lived at his home, The Narrows, which was located in the new county of Westmoreland, formed from Northumberland in 1653. Colonel Allerton was the son of Isaac Allerton, who came to Plymouth on the _Mayflower_ in 1620, and of Fear Brewster, only daughter of Governor William Brewster, of Plymouth. He was born in 1630 and was one of the early graduates of Harvard College. He came to Virginia and settled in the Northern Neck at The Narrows. From Ursula and Isaac Allerton was descended President Zachary Taylor. _WITCHCRAFT_ The belief in witchcraft was prevalent amongst the early settlers of the Northern Neck. The Neck at this time was beset with wolves and Indians and was a true type of a frontier colony. To the witch was ascribed the power of inflicting strange and incurable diseases, of changing men into horses when they were asleep at night, and after bridling and saddling them, riding them at a gallop over the countryside to the places where the witches had their frolics. Horses too were thought to be ridden at night, unbridled and barebacked. In the morning these horses would be fagged-out and caked with sweat and mud and their manes plaited into "witches' stirrups." That witches were taken seriously by settlers of the Neck in the seventeenth century is proven by the following abstract from the Northumberland County records: "20 Nov., 1656. "Whereas, Articles were Exhibited against Wm. H---- by Mr. David Lindsaye (Minister) upon suspicion of witchcraft, sorcery, etc. And an able jury of Twenty-four men were empanelled to try the matter by verdict of which jury they found part of the Articles proved by several depositions. The Court doth therefore order yet ye said Wm. H---- shall forthwith receave ten stripes upon his bare back and forever to be Banished this County and yet hee depart within the space of two moneths. And also to pay all the charges of Court." _SEAHORSE OF LONDON_ On a cold day in the late winter of 1657 some men were busily working in the Potomac near the mouth of Mattox Creek. They were trying to lift a foundered ketch, the _Seahorse_ of London. Among the men was young John Washington, son of an English clergyman. John had sailed for Virginia in the winter of 1656, as mate and voyage partner in the _Seahorse_. After arriving in the Potomac the ketch was loaded with a cargo of tobacco. On her way out of the river she ran aground. Before she could be floated a storm hit and sank her. The entire cargo of tobacco was ruined.
