Mary Ann is born on June 7, 1853 in Scarborough Township, Canada West, the daughter of Thomas Thomson (1827-1909) and Mary Ann Hipkins (1832-1867). She is baptised on July 4, 1853 in Scarborough. Scarborough Township is now a part of the city of Toronto, Ontario, Canada. (The birth record spells her name “Mary Ann,” and the wedding record spells it “Mary Anne.”)
In the 1861 census, Mary is seven years old, living with her family in Pickering Township, the next township east of Scarborough. The family appears to be living in the village of Pickering (as compared to on a farm in Pickering Township) and Mary Ann’s father is probably a shop keeper (the writing on the census record is difficult to read).
Her mother dies in 1867 and two of her siblings go to live with their grandparents in Scarborough. It is not known what happens to Mary– presumably she moves with her father at some point to Brampton in Peel County where her father operates a fruit store. Her father re-marries in 1870. Neither she nor her father can be found in the 1871 census.
Mary Ann (or Anne) marries George Arthur Baker c1845-? on December 4, 1873 in Brampton and the wedding record shows her residence at the time is Brampton (supporting the idea that she moved with her father). George Baker was born in London, England. In the 1881 census Mary and George are living in Toronto with their first child, Sidney. George appears to be a “commercial traveller” which probably means he is a salesperson. Mary and George have two more children (probably one, Georgina, dies as an infant). With one exception no records for Mary or George have been found after the 1881 census. However, as it is known that the second child, Georgina, is born in Toronto in 1879 and the third child, Albert H., is born in Detroit, Michigan in 1885, the assumption is that the family moves to the United States sometime around 1882. They have not been found in any US census records.
Mary and George have the following children:
The one exception to records being found after 1881 is the Canadian 1901 census. Mary and her son, Albert, are living with Mary’s brother, Albert Wales Thomson in the town of Galt, Ontario. Albert Wales is a hotel keeper. The census record has an “M” in the column noting marital status beside Mary’s name. This indicates that she is married (as opposed to “W” for widowed). The question is: Where is her husband, George? Her oldest son, Sidney, was married in 1900 so that explains why he is not with his mother. No answer to this question has been found: perhaps George Baker had died and the census taker mistakenly put an “M” instead of “W” in this column; perhaps Mary and George have separated; or perhaps there is some simpler explanation such as Mary just visiting her brother for a while. Whatever the correct answer, neither Mary nor George can be found in any census record (Canada or the United States) after this point.
 1968 Paterson family tree shows Mary Ann, her spouse, 2 children & descendents.
 Scarborough Birth Register (poor photocopy of transcript): Mary Ann born June ?7/53, baptised July 4/53
 1861 census, Ontario, Ontario County, Township of Pickering, pg 12, lines 1-6: Thomas Thompson (sic) (25); Mary A. (21); Mary A. (7); Albert E. (6); Agnes H. (4); Rosinia Hipkins (22). It shows all person born in U.C. [2 were born in England]. While it is not possible to make out the occupation for Thomas [the word appears to contain the following letters “S” or “L” “Th??por”], it is to be noted that reading the occupations of others on this census page – Inn Keeper, labourer, servant, minister, etc – the word “farmer” does not appear leading to the speculation that the Thomson family was living in a village.
