MARY BLACKMAN

In the Charles county Gentry by Harry Wright Newman, is a chapter on the Dent Family. When he got to John Dent, which I call "III", on page 64, he states that Mary, his wife was probably connected to the Blackman family as there were at least three of her grandchildren that carried the name, such as Thomas Blackman Davis, son of Anne Dent and Charles Davis, born 1782.

From the State of His Lordships Manor of Beaverdam in St. Mary's County, March 1768, image 378 on Family Search Full text Search
is a record of Beaverdam Property listing that The original property was taken over by Thomas Blackman on June 10, 1743. It had 211 acres and at the time John Dorsey was tenant in position, the annual rent was 1.4.4 and the fines were 4.17.4, and WAS now in the possession of Tabitha Dent, age 25. Tabitha was the granddaughter of Thomas Blackman, and daughter of Mary Blackman. Lovely to have that connection made.

Mary Blackman was born about 1714 possibly in St. Mary’s County, Maryland. Her parents we now believe because of that property statement were Thomas Blackman and either Ann or Elizabeth Brewer. I'll explain the confusion on the mother's file.

The Blackman's were actively involved in the community as were the Dent family. They were land owners, and occurred often in court records as witness to wills and serving the community.

Mary wed John Dent III in Charles County Maryland about 1735. The Dent family has connections to Newport, in Charles County and Chaptico Hundred in St. Mary’s County. The two sites are near each other at the county line.

John's father, John Dent II died intestate in 1733. His eldest son, our John Dent III inherited the estate "Dent’s Inheritance. John III divided the estate of 1169 acres amongst all his brothers.

The Charles County MD 1733 Tax List has John Dent (III) as 1 taxable individual in Newport West side Lower Port.

The children of Mary and John Dent were:
1. John Dent IV born about 1736
2. Mary Dent born about 1738
3. Hatch Dent born1751, died 1819
there was a Hatch Dent son of Hatch Dent who this may be confused with
4. Sarah Dent born about 1742 married John Clark
5 Tabitha Dent born 1743, wed Walter Moreland died after 1790
6. Anne Dent born about 1745 wed Charles Davis
7. Bennett Dent born about 1747

John III made various conveyances of land from 1757 to 1777. Each time Mary waived her dower rights. The properties were on the north side of Piles’ Fresh., which is how we know her name was Mary. Charles County Deed Book V, no 3, page 201

John Dent III took the oath of allegiance to the State of Maryland in Charles County in 1778. Found in the DAR library Unpublished Maryland Records Vol. 5.

John Dent III made a will dated December 21, 1788 and proved August 22, 1791. Charles County Will book AK No 11, page 28. Mary, his wife is not mentioned so we assume she had died sometime between 1777 and 1788.

It is not known where she is buried. But it could have been on Dent's Inheritance.
