While serching for information on my grandmother, Katherine (Hallinan) Kehoe, I came across some Sarjeant information.My grandmother's sister Ursula Hallinan b. 1891, d. 1972, married Walter Sarjeant, b. 23 Jan. 1886, d.15 Sept. 1956. They had one son, Walter B. Sarjeant who married Margaret H. Laurie.They had two boys; Dr. W.J. Sarjeant of Amherst, N.Y. and R.B. of Sudbury, ON. During the last couple of centuries, the 'Latter Day Saints' kept very detailed historical information and this is available on the internet.It carries a multitude of family histories including Canada's 1881 census. There is a section where people can submit family information.David King Sarjeant has posted details about the Sarjeant famiily.If David is a relation of yours, you probably already have this information.If not, you might find some help there. Good luck with your search.
