Notes:

In the 1871 census for Toronto, William's occupation was listed as "turnkey" - an employee in a jail.

William married Sarah FRASER. Sarah (daughter of James FRAZER and ELIZABETH) was born on 6 Jun 1826 in Tempo, County Fermanaugh, Ireland; died on 13 Aug 1920 in Toronto Ontario. [Group Sheet] [Family Chart]

Notes:

Sarah's birth date was given in the 1901 census as 6 June 1826. Her year of immigration was given as 1844.

Sarah's obituary in the Aug. 14, 1920 edition of the Toronto Daily Star:
"There died at her late residence, 114 Delaware Avenue, a resident of Toronto for about 75 years, Mrs. Sarah Cassidy. Mrs. Cassidy was the widow of the late William Cassidy, who was the first W.M. of King Solomon's Lodge, A.F. and A.M., Toronto. She was favoured with good health until about three weeks ago, when she fell and fractured her wrist, and was unable to withstand the shock. She leaves one son, Solomon, of the Globe, and one daughter, Mrs. George W. Sharp, Delaware Avenue.
Mrs. William Cassidy was born in Tempo, Fermanaugh County, Ireland, June 6, 1826. She was the last surviving member of the family of James and Bessie Fraser, of Tempo, and on the death of her parents emigrated to Canada at an early age. After a brief residence in Quebec and Montreal she located in Toronto, where she has since resided."

Notes:

A clue to James Frazer's parents has come from recent autosomal DNA testing. We match on a portion of chromosome 12 with a group of people who are known to descend from Richard Frazer, born ca. 1777 [ a relevant blog is at http://www.jmhartley.com/HBlog/wp-content/uploads/2015/08/Archibald-Line-Chart.jpg]. This Frazer line was in Aghrafinigan in County Roscommon. Richard Frazer had several children, including a James, of whom no data is presently known. More is known about some of Richard's other children and their descendants. Richard's parents are said to be Archibald Frazer (ca. 1743) and Mary Lilley. A web page of Frazer ancestors is at http://jmhartley.com/Frazer/frazerupd0001.htm.

The names and birthdates of the children of James and Elizabeth Frazer are taken from their son John's family bible. On another page of the same bible is the inscription " James Frazer Departed this Life January the 15th 1835."

That bible also had a page with the following:
"Mary Ann Caruthers, her book dated this 18th day of July, 1836",
and on another page:
"Sarah Caruther, Robert Caruthers".

A James Frazer is listed as occupying lot 23, concession VI (west side of Huron St.) in the 1843 Chingacousy Township assessment roll, according to the book "people of Peel".

James married ELIZABETH. died in UNKNOWN. [Group Sheet] [Family Chart]

Notes:

The names and birthdates of the children of James and Elizabeth Frazer were recorded in John Fraser's (their son) family bible, which in turn was transcribed in notes made by Lola (Passmore) Falconer. John Fraser's bible also contained "Mary Ann Cauthers Her book dated this 18th day of July 1836", and on another page, the names "Sarah Cauther" and "Robert Cauthers". It is possible that Elizabeth's maiden name was Caruthers, although no records have been found to substantiate this.
