The records recorded in the Tithables of Lancaster County provides the following information about Matthew Bentley:
Matthew and Mary Willis where married in Middlesex (formerly a part of Lancaster) on February 6, 1670 (it is estimated he was born approximately 20 years earlier in 1650). Mary Willis is listed as widow, and Matthew Bentley a shoemaker. The marriage contract also makes provision in favor of her children, Richard, John and Eleanor Willis. This Mary Willis was doubtless the widow of Thomas Willis. Her second husband, Matthew Bentley, was one of the leaders of the adherents of Nathaniel Bacon in Middlesex and vicinity"
In February, 1677, Matthew Bentley was summoned to a Middlesex Court to answer the charge that "during the late rebellion, when in command of forty or fifty men-in-arms at Major Lewis' plantation, in New Kent county, he killed three hogs and four sheep, used a great deal of corn, and took meal for the whole rebel army at Major Pate's. Bentley took an appeal to the General Court regarding this case.
On May 3, 1677 William Ball and Walter Whitaker made a statement, "that one Bentley, a shoemaker of Middlesex County, played a great part in the late rebellion but though first imprisoned, he was freed, by order of Major Beverly and not brought before court".
On July 23d, Colonel Christopher Wormeley, of Middlesex, sued Matthew Bentley and others for trespass and for taking from him in October, 1676, twelve beeves, forty sheep, twelve bushels of salt, etc. He obtained judgment for 435 pounds.
March, 1677, Mr. William Gordon and Mr. Alexander Smith, of Middlesex, became securities for the good behavior of Matthew Bentley.
The will of Matthew Bentley, dated January, 1685-6, was proved in Middlesex February, 1685-6.
He left Mary Allden a young mare; Robert Allden "a cloth serge suit I now have and my great cloth coat; " John Willis his broadcloth suit with gold buttons on it; son, Richard Willis, executor, and to have the remainder of his estate.
Matthew Bentley died January 8, I685, and Mrs. Mary Bentley September 27, 1684.
See also "The records of Henrico County contain sundry charges of depredations committed by Bacon's soldiers, showing that the people's cause was strong in that section. Major John Lewis, of Middlesex, laid claim of damages at the hands of "one [Captain] Matt Bentley," with "forty or fifty men-of- arms," in the time of the late rebellion." Major Lewis's inventory of his losses includes "400 meals" (which he declares were eaten at his house by Bacon's men during their two days encampment on his plantation), the killing of some of his stock, and carrying off of meal "for the whole rebel army," at Major Pate's house, at whose house Bacon died in October 1676 ." also see 
Another source states: "Two Baconians, Matthew Bentley and Robert Boodle, married wealthy widows and were not given the social position in the county as the prior husbands maintained. Riding with Nathaniel Bacon could be a substitute position they never held. The two native Middlesex sons had been cut from their family inheritances by circumstances out of their control". 
More information is needed to document Matthew's date of birth and early life.
