Dr. Josiah Sturtevant 1720 - 1775

Dr. Thomas Sturtevant was a son of Dr. Josiah Sturtevant, a physician in practice in the town of Halifax before the Revolutionary War. He early espoused the cause of the king, and on account of his pronounced utterances against the patriot cause, was compelled to leave the town and flee to Boston. He was there appointed a surgeon in the British army, but died soon after, and was buried under the Old South Meeting-House, Boston. The following letter illustrates the feeling that existed at the time on the part of the loyalists :

August 18, 1775.
My dear husband departed this life at Boston in his fifty-fifth year where he was driven by a mad and deluded mob for no other offence but his loyalty to his sovereign. God forgive them and grant that his death may be sanctified to me and our children for our souls everlasting good. Lois (Fuller Foster) Sturtevant.

According to the records at the Old North Church, over 1,100 people were buried in the Crypt under the church. Since Dr. Josiah Sturtevant was Anglican, and a supporter of the King (Loyalist), it is very likely that he was buried there, despite not having his name on the list.
