Mary Luker
The Dougherty family came to Utah between 1852 and 1855. Son William was born in New Jersey in March 1852. The first documentation to place them in Utah are Salt Lake 12th Ward records in 1855. Further research is needed to confirm the year of their travel and the name of the pioneer company they traveled with.
The Utah State History Cemeteries and Burials database shows their names as follows: "Dark Dockaday" (likely misread from the original "Danl" Dougherty), Mary Dougherty, and "William Dougherty." The family was buried together in the Salt Lake City cemetery, on B5 13E, and in plots 1E, 3E, and 4E. No gravestone is shown on the Find a Grave website.
There is a discrepancy in Mary's year of birth. Family Tree shows her birth date as 7 December 1826, but the 1850 New Jersey Census and the 1860 Utah Census both show her as being born about 1828. The Utah State History Cemeteries and Burials database shows her birth as 7 December 1830.
The New Jersey Marriages shows her maiden name as "Lewker."
In some sources their surname is listed as "Daugherty."
