Given the age difference betweeen Hugh & Margaret, it's likely he had a prior wife.

Kinsey, Hugh, A.A. co., 6th May 1667; To grandson Paull Kinsey, "Walnutt Neck." To Sara Clarke, grandchildren Hancock Ball and Margaret Kinsey, and Charles Gorsuch, personalty. To wife Margaret, residue of estate, real and personal. To young. dau. Eliza: Kinsey and hrs., said estate at death of wife afsd. In event of death of said Eliza: without hrs., estate to pass to Mary Humphreys, at whose death, sd. estate to be divided among rest of testator's children, equally. Test: Wm. Hare, John Malom. 1. 291.

Sons Paul and Daniel must be deceased.

Grandchildren Paul and Margaret KINSEY are presumably children of Paul and/or Daniel, or possibly some other son unknown to us.  I'm inclined, however, to believe they are the children of Paul KINSEY because, other than his being transported in 1662 by his father, there is no mention of Daniel anywhere in the records of VA or MD, which suggests he died early on.

Sarah CLARKE is Hugh's daughter, wife of Abraham CLARK.

"Hancock Ball" is Hannah BALL, Hugh's granddaughter, the daughter of Mary (KINSEY) HUMPHREYS BALL.

Mary HUMPHREYS, as referred to here, must mean Hugh's granddaughter, the daughter of Thomas & Mary (KINSEY) HUMPHREYS.  Mary HUMPHREYS, "Jr.," never married, so without a husband, would have had special need for the bequest, which may be the reason she was favored in this way.  When Mary HUMPHREYS, Jr., died, her parents and Hannah BALL's parents were already deceased.  The BALL family took legal action to have Mary's estate fall to her half-sister, Hannah BALL, rather than back to the KINSEY heirs.  They succeeded.

The genealogy of Charles GORSUCH is well known (see source below), but he appears to be no relation to Hugh.  Though Charles GORSUCH fell on hard times ca. 1680s/90s, he was, at one time, a major landowner in Baltimore Co., owning 5000+ acres, including the land on which Baltimore Town was laid out.

p. 171	Thomas Sparrow, who on 13 May 1701 sold to Thomas Rider, who on 1 Sept 1702 sold it to George Valentine (IR # PP, 139).

This Thomas SPARROW has to be Hugh's grandson because his son-in-law, Thomas SPARROW died in 1774/5.

Elizabeth, wife of Richard Johns, was his youngest daughter.  She died February 1, 1715-16...

Co., Baltimore, MD (issued 1996 as Broderbund CD-162).

p. 245	The record of the establishment of this little colony, stretched along the north shore of the Patapsco and made up of various members of the Gorsuch family, would appear to begin with an entry in the Maryland Land Office records which reads "July 16, 1659, Warrants granted the undersigned conditionally that they enter Rights and seat their land between this and the 25th of March next:  Thomas Powell 700 acres; Walter Kickinson 600 acres; Robert Gorsuch 300 acres; Richard Gorsuch 300 acres; Howell Powell 300 acres; William Ball 500 acres; William Clapman jur. [sic jnr.] 500 acres; Richard Ball 500 acres; Thos. Humphry 600 acres; Hugh Kensey 400 acres" (Md. Patents Vol. IV, fol. 54). Most of these names occur soon after in the Quaker records of the province, so that is seems quite probable that they were a little group of Quaker colonists who had come up from Virginia to take up the recently opened lands on the Patapsco in Baltimore County, which appears to have been erected into a county this same year.  The Gorsuches, Powells, Claphams, Dickensons, Balls, Kinseys (Kenseys) and Humphreys are known to have come from Lancaster County, while the Todds, who came a year or two later, were from Gloucester.  That the conditions in regard to entering their rights and seating their lands were complied with by the warrantees is shown by the subsequent entries in the records of the Land Office of certificates of survey and, finally, by the issuance of patents to all whose names appear in the warrant of 1659.  July 28, 1659, a tract of 500 acres called "Gorsuch" was surveyed for Robert Gorsuch, planter, on the north side of the Patapsco river "respecting" (i.e., opposite) the land of Hugh Kensey on the south side of the river (Md. Patents, Vol. IV, fol. 228)...
p. 246	...Charles Gorsuch, August 3, 1661, had surveyed for him "Whetstone Point," 50 acres comprising that part of the present city of Baltimore now occupied in part by Fort McHenry... William Ball and Richard Ball, each of whom received warrants for 500 acres of land under the warrant of 1659 and became settlers on the Patapsco, have been shown by Dr. Christopher Johnston to be the sons of Colonel William Ball of Lancaster County, the progenitor of the distinguished Virginia family of that name (Virginia Mag. Vol. VII p. 440 and Vol. VIII p. 80)*. Hugh Kinsey and Thomas Humphrey have been shown by Mr. Miles White, in his Ancestry of Johns Hopkins, to have also come from Lancaster County (Publications Southern Historical Association, Vols. IV, p. 395 and V, p. 360)... ...many if not all of these first actual settlers [those named in the Warrant of 1659] were probably a group of friends who came up together from Lancaster County and that the probable motive of their migration was religious persecution, as most of them are known to have been Quakers, and it was at this time that Virginia began to put into full effect the various repressive measures against the numerous recent converts to this sect in order to drive them out of that colony. *Genealogies of Virginia Families (Genealogical Publishing Co., Inc., 1981), Vol. I, 23-27.
p. 387	...He [Charles Gorsuch] probably became a convert to Quakerism before leaving Virginia and was one of the group who removed from there to the Patapsco in 1659 to avoid religious persecution... There are a few chance references to him in several early wills. Hugh Kinsey [Kensey] of Anne Arundel County in his will dated May 2nd, 1667, leaves his sac cup to Charles Gorsuch and his heirs (Annap. Test. Proc. 2: 188)...

Mary Kinsey	1643	Princess, Anne Arundel, MD	1668	-	March 1661	Lancaster, VA	Richard Ball	Hugh Kinsey	Mary Humphrey

Mary KINSEY's mother was Margaret COULTON, not Mary HUMPHREY(S).  Mary KINSEY is Mary HUMPHREYS!  That is, Mary KINSEY is Mary (KINSEY) HUMPHREYS BALL.  Mary KINSEY, daughter of Hugh KINSEY, married first Thomas HUMPHREYS and second Richard BALL.  Also, Mary was born in England.
