I have researched Urquharts in Toronto, but have not yet come across one that married a McGolpin. That is certainly not a common name. There are only two instances of it on the Morman website: http://www.familysearch.orghttp://www.familysearch.org
Once in the 1881 Canadian census:
John MCGOLPIN, Married, Male, Irish, 44, Ireland, Baker, Methodist Canada
Jane MCGOLPIN, Married, Female, Irish, 40, Ireland, Methodist Canada
William MCGOLPIN, Male, Irish, 22, Ontario, Tinsmith, Methodist Canada
James MCGOLPIN, Male, Irish, 20, Ontario, Tinsmith, Methodist Canada
Jane MCGOLPIN, Female, Irish, 17, Ontario, Dress Maker, Methodist Canada
Ellon MCGOLPIN, Female, Irish, 14, Ontario, Methodist Canada
Sarah MCGOLPIN, Female, Irish, 12, Ontario, Methodist Canada
Census Place St Thomas Ward, Toronto, York, Ontario
Family History Library Film1375882
NA Film NumberC-13246
And, once in the birth records:
Sarah McGolpin, female, birth 22 JUL 1892 in Toronto, York, Ontario. Parents: Father:William John McGolpin, Mother:Susan Wilson.
The 1901 and 1911 Canadian census, with index, are on website: http://automatedgenealogy.com/census/index.htmlhttp://automatedgenealogy.com/census/index.htmlHere's the only family with the correct spelling in the 1901 census:
30/150 McGolpin Jane, Female, Head, Widow, Jun 30 1838, age 62, Ireland, immigrated 1864, Irish, Methodist, no occup.
31/150 McGolpin Nellie, Female, Daughter, Single, Oct 31 1872, age 28, Ontario, Irish, Methodist, no occup.
32/150 Dunbar Maggie, Female, Boarder, Single, Oct 7 1874, age 26, Ontario, Irish, Presbyterian, dressmaker.
On the website: http://freepages.genealogy.rootsweb.com/~wjmartin/wm-index.htmhttp://freepages.genealogy.rootsweb.com/~wjmartin/wm-index.htmof the Wesleyan Methodist Baptisms, there is one entry:
Vol.4, Page 290, York County, Toronto city, child: William Carr McGolpin, father: James A., mother: Anne, residence: Toronto, birthplace: Toronto, birthdate: 1887-07-04, baptism date: 1887-11-23, baptism place: Toronto, minister: Rev.Manley Benson.
Do you have any dates and places of birth, marriage, death and burial for your Urquharts and McGolpins?
