I note in the PANB index of land petitions one Reuben Chase. Assuming it is the same person, he petitioned for land in Queens Co., NB in 1786 and 1789, but more significantly in Sackville, Westmorland Co., NB in 1808 with, amongst others:
EASTEBROOKS, JAMES
EASTERBROOKS, DANIEL
EASTERBROOKS, SAMUEL
EASTERBROOKS, THOMAS
EASTERBROOKS, WILLIAM
The name seems to have persisted in the area for several generations. Martha, wife of Reuben Chase, d. Upper Sackville 21MAY1877 age 64 years and 5 months. A Reuben Chase of Sackville d. Lowell, MA in 1853 and in 1888 his remains were conveyed to Sackville for reinterment with his wife. Reuben Chase m. Sackvillle 1JAN1880 Famicha Bower Kerr. This suggests several geneations.
See:
http://www.oulton.com/cwa/newsns.nsf/a6040306c38ac84d8525658...which in part, has:
"I assume that Reuben, the fourth child of Jethro also lived in Sackville, NB and married (1) Rebecca Lawrence on October 23, 1806 and married (2) Sarah Ayer on November 30, 1808. Reuben died on December 19, 1853 in Lowell, Mass. Sarah Ayer had previously married Robert Atkinson. Can anyone confirm this?"
http://www.pa-roots.org/data/read.php?3528,649935One inaccessible site has:
Reuben Chase Sr
Birth: About. 1775
Death: 1853 in Lowell, Massachusetts
Sex: M
Father: New England Planters b. 1760
Mother:
Spouses & Children
Sarah Ayer (Wife) b. About. 1778
Marriage: 1808 in Westmorland Cty, NB
Children:
Mary Ann Chase b. About. 1808
Reuben Chase Jr. b. About. 1810
Eliza Chase b. 1817 in Sackville, NB
Chipman Chase b. 1821 in Sackville, NB
suggesting children by his 2nd wife, but not by his 1st. Since William and Miriam had a son, Reuben, a connection seems possible.
There appear to have been two Reuben's early on. At:
http://www.nbgs.ca/firstfamilies/FAMILY-C-2006.pdfis mentioned one in Gagetown, Queens Co., NB. His son-in-law is given as Tertullus Dickinson (the younger), whom, I believe, was later in Carleton Co. This suggests to me that this Reuben (whom I assumed to be the same above) was different. In fact, he died in Queens Co. and died or was buried 20FEB1820 age 81 years.
There is also a mention of Isabel Copp b. NS 1792 who m. Reuben Chase.
I note at:
http://freepages.family.rootsweb.ancestry.com/~corbeil/purdy...it is stated that "a record of the marriage rite performed by Rev. Chris. Milner between the years 1820 and 1830 inclusive:", includes for 1825 (rather than 1835; perhaps an error?):
William Chase and Mariam Estabrooks
apparently both of Sackville. The Rev. Christopher M. Milner (Anglican I Believe) was rector in Sackville from 1820 to 1835. He later died in Sackville (1877) and was buried there. Apparently the Anglican Church Records for St. Paul's in Sackville 1825-1839 are on microfilm F-1124. Other records (1825 (1820 elsewhere)-1971) are on F-1125 but are restricted and require permission (probably from the bishop in Fredericton.)
This is likely old ground for you, but I would suspect that somewhere in there is William's family.
