He had four children by his wife Sarah. His second wife, Elizabeth, he married October 6, 1703; she was the widow of William Greenough and the daughter of Increase Mather.

Mather Byles, D. D., son of Josiah and Elizabeth, was born in Boston in 1706. He graduated from Harvard University in 1725 and was ordained first pastor of the Hollis street church in 1733. This church was built on land given by Governor Belcher in 1733, the site is now occupied by the Hollis street Theatre. He married, February 14, 1733, Mrs. Anna Gale; the ceremony took place in the state room of the Province House, Rev. Thomas Prince of the Old South officiating. By this marriage he had six children born, all of whom died young except Elizabeth. His second wife was Rebecca, daughter of Lieutenant Governor Hon. William Tailor; the ceremony was performed by Rev. Joseph Sewell, D. D. By his second wife he had four children. He was created Doctor of Divinity at Aberdeen in 1765. He lived happily with his parish until 1776 when the connection was dissolved and never renewed. Of the Congregational clergy he stood alone against the revolution.

Mather Byles is one of the most interesting men of this period. He was a scholar and a great wit. Pope, Lansdowne and Watts were among his correspondents. In his pulpit he avoided politics and on being asked the reason, replied: "I have thrown up four breastworks, behind which I have entrenched myself, neither of which can be enforced. In the first place I do not understand politics; in the second place, you all do, every man and mother's son of you; in the third place you have politics all the week, pray let one day in seven be devoted to religion; in the fourth place, I am engaged in work of infinitely greater importance; give me any subject to preach on of more consequence than the truth I bring you, and I will preach on it the next Sabbath."

The preacher became known as the "celebrated Dr. Byles." He wrote in poetry and prose very well, and some of his sermons are still extant. Also several of his essays, in the New England Weekly Journal, a poem on the death of George I; and the accession of George II, in 1727. A sort of memorial address to Governor Belcher, on the death of his wife, and a poem called the conflagration, and a volume of metrical matters published in 1744.

The serious writings of Dr. Byles are singularly free from everything suggestive of frivolous association. In his pulpit there was none of it, while out of it, unless on solemn occasions, there was very little else. One of that day said his wit at times was quite as clever as Jonathan Swift or Sydney Smith.

Mather Byles and his family were staunch loyalists. News of the repeal of the stamp act arrived in Boston May 16, 1766. The nineteenth of May was appointed for merry-making. "At one in the morning the bell of the Hollis street church began to ring," says a zealous writer of that day. "The slumbers of the pastor, Dr. Byles, were disturbed of course, for he was a tory, though a very pleasant tory, after all." In 1777 he was denounced in town meeting, and having been by a subsequent trial pronounced guilty of attachment to the Royal cause, was sentenced to confinement, and to be sent to England with his family. This Byles steadfastly refused to do and the doom of the banishment was never enforced, and he was permitted to remain in Boston. The substances of the charges against him were that he continued in Boston during the siege; and that he prayed for the king and the safety of the town.

For a time he was kept a prisoner in his own house. On one occasion while under guard he persuaded the sentinel to go on an errand for him, promising to perform sentinel's duty himself; and to the great amusement of all gravely marched before his own door with a musket on his shoulder, until his keeper returned. This was after his trial; and alluding to the circumstances that he had been kept prisoner, that his guard had been removed and replaced again, he said, that "he had been guarded, re-guarded, and disregarded."

REV. MATHER BYLES, D. D.
Born in Boston in 1706. "A man of infinite wit." Died in Boston July 5, 1788.

Near his house, in wet weather, was a very bad slough. It happened that two of the selectmen who had the care of the streets, passed that way driving in a chaise, stuck fast in this hole, and were obliged to get out in the mud to extricate their vehicle. Dr. Byles came out, and making them a respectful bow, said: "Gentlemen, I have often complained to you of this nuisance, without any attention being paid to it, and I am very glad to see you 'stirring' in this matter now."
