6 January 1787 - the first mention of John Barrett in Plymouth records, this is the date his intention to marry Hannah Holmes was filed. It says:
1787 Janry 6 John Barrit now resident in Plimo & Hannah Holmes of Plimouth
It seems John did not come from Plymouth originally.
2 September 1787 - They are married in Plymouth
These 2 events are documented in Plymouth records.
About 1788 - Their son, William Barrett, is born (birth not recorded in Plymouth)
About 1789 - They may have had a daughter (birth not recorded in Plymouth)
1790 Census - John Barrett is in Plymouth, Massachusetts with 1 male age 16 and older (himself), 1 male age 16 and under (William), and 2 females (his wife and perhaps a daughter)
Between 1790-1800 - I can only speculate that John Barrett died. There is no record of his death in Plymouth.
Also between 1790-1800 - They may have had a daughter (birth not recorded in Plymouth)
1800 Census - Hannah Barrett is in Plymouth with 1 male age 10 to 15 (probably her son William), 2 females under the age of 10 (daughters?), and 1 female age 26 to 44 (Hannah, placing her birthdate between approximately 1756 and 1774)
With regard to the parents of Hannah Holmes, I am currently going through the process of locating every Hannah Holmes born in Plymouth between roughly 1756 and 1774, and trying to find out which one she might be. Holmes is a fairly common named in Plymouth.
2 November 1803 - Hannah Barrett dies in Plymouth, leaving a 15-year-old son (my ancestor William) and possibly 2 daughters, maybe the first about 13 or 14 and the second anywhere from 3 to 10.
15 November 1803 - Coroner Stephen Sampson was paid $14.15 for taking an inquisition on the body of one Hannah Barrett. (Plymouth Court Records, volume 4, page 177)
A friend checked the Plymouth County Massachusetts probate index, 1686-1881 by Ralph V. Wood (Published in 1988, Picton Press (Camden, Me)) and did not find any probate on the family.
I am left to wonder what happened to the 3 (?) minor children when their mother died.
20 May 1808 - William Barrett files his intention to marry Ruth Westgate of Rochester, MA (she had already given birth to their first child, William, on 19 May 1808)
They are married almost immediately and have a total of 7 children (as far as we know).
1810 and 1820 - William Barrett appears in the censuses in Plymouth, and the family numbers match up with the number of adults and children they were known to have.
17 Oct 1826 - William dies before this date, when Plymouth church records show the death of "the widow Barrett's child" at the age of 4 (presumably their youngest daughter, Susan, who was born about 1822).
The first five children (William, John, Clarissa - my 4th great-grandmother, Ruth Ann, and Benjamin W.) all went on to have children. I do not know what happened to the 6th child, Charles, born about 1821, and Susan was the 7th child.
1830 Census - Ruth Barrett appears in Plymouth
12 December 1836 - Ruth (Westgate) Barrett remarries to Martin Gould in Plymouth, MA.
29 December 1861 - Ruth (Westgate) (Barrett) Gould dies in Plymouth.
Death records of the first 5 children of William and Ruth Barrett verify their parents (except Ruth Ann (Barrett) Savery's, which gives her father as "Charles Barrett"; clearly an error).
Who were the parents of John Barrett and Hannah Holmes?
Where did John Barrett come from before living in Plymouth? When did he die and how?
I should note that I found no land transactions for John Barrett whatsoever, nor Hannah in the time period during which they were alive.
When and how did William Barrett die?
Having exhausted Plymouth vital, church, and court records on this family, I am trying to find out if coroner's records are available. I am looking at each and every John Barrett and Hannah Holmes born in the correct time period.
I am also looking at all women living in Plymouth in the 1850 census who were born between 1787 and 1799, then checking their death records (or whatever further records are necessary) to see if any might be a daughter of John and Hannah.
Of course, this last one can only eliminate so many women. The Barrett daughters may have died before 1850, or moved to another town, county, or state.
However, the process of elimination seems to be the only avenue I can pursue at this point.
