John Thomas Mason Burbridge was my great-great grandfather. Here's what I have about him:
John Thomas Mason Burbridge came to Mississippi from Maryland in 1836. He practiced law and was a probate judge in Panola County from the time the county was formed until his death.
A John Burbridge is listed in the 1810, 1820, and 1830 censuses for Allegany County, Maryland, but this is certainly not John Thomas Mason Burbridge and almost certainly not his father--the numbers of children of various ages and both sexes does not match any other known records about this Burbridge family.
His parentage is uncertain. Although at least one online source gives his parents as John Burbridge and Charity Dowden, the 1880 US Census lists both his parents as having been born in Virginia. John Burbridge was born in Wiltshire, England, although documentation of this is shaky, and Charity Dowden was born in Maryland. However, it is almost certain that his mother died and his father remarried Frances R. Davidson, who was the mother of his (probably half-) sisters, Fanny Ann and Mary Emma Burbridge.
A letter to him from Hanson Briscoe Pigman dated 6 Feb 1840 tells him of the death of his friend and the writer's brother Philip Augustus Pigman (born 31 Mar 1812), who was described in a note on the address portion as "Cousin Hattie's father." Philip's wife was Fanny Ann Burbridge Pigman (born 7 Mar 1811 in Rose Hill, Cumberland, Allegheny, Maryland; died 17 Apr 1873). A lock of hair is enclosed in the letter, presumably Philip's. Cousin Hattie was Harriet Burbridge Pigman (born 12 Jun 1838 in Cumberland, Maryland), who married Henry Hobart Keech on 25 Jan 1860 in Maryland, and who died in 1925 in Fredericktown, Maryland. Wylie Pope Burbridge named his first daughter Hattie Keech after his cousin.
There is another letter to him from Hanson Pigman dated 25 Oct 1845 offering sympathy on the death of his (Burbridge's) wife. This means that Lucy Gooch Barnett must have been his second wife, as John and Wylie Burbridge were both born after that date. The first wife's name was not given in the letter, but may have been named Margaret Goode. Lucy Gooch Barnett was known in the family as "the widow Barnett," implying that she had been married to a man named Barnett. His third wife was Sarah "Sallie" A. Nichols, whom he married some time after Lucy's death in 1852.
John and Lucy were the parents of three children: Mary J. B. Burbridge (born abt. 1846), John Burbridge (abt. 1847-abt. 1870), and Wylie Pope Wooten Burbridge (13 Dec 1850-16 Jan 1932).
He is listed in the 1850 Slave Schedule for Panola County, Mississippi, District 13, as owning two slaves: a 55-year-old woman and an 11-year-old girl.
At the time of the 1860 census his real estate was worth $4000, as was his personal property [$95,887 each in 2010 dollars].
