I found your folks in the June 11, 1900 White Street, Saratoga Springs Ward 5, Saratoga Co., New York State census on www.ancestry.com
Murt? Urquhart, head, July 1855, 44, married 16 years, born Scotland, father born Scotland, mother born Scotland, immigrated 1885, mason
Selma Urquhart, wife, Jan 1855, 45, 3 out of 3 children alive, born England, father born England, mother born England, immigrated 1886,
Lillian Urquhart, dau, March 1844, 16, NY SCT ENG, at school
Hugh Urquhart, son, Dec 1885, 14, NY SCT ENG, at school
Victor Urquhart, son, Sept 1896, 3, NY SCT ENG
I will submit the name corrections to Ancestry. Always remember that birthdates and ages were not always correct on the census. Sometimes people didn't know, or they lied because they didn't trust the government.
The Scottish began civil record taking in 1855. Their records are full of information. There is a great pay-per-view website www.scotlandspeople.gov.ukPerhaps you would find Murdo's birth certificate. It is always good to look at the LDS microfilm of parish registers for baptisms in Scotland, if you know where a person was born. The LDS website is www.familysearch.orgAlso, a NY death record would be good to have.
