Hi
According to my Mackenzie information Janet Fraser and William Mackenzie married in Loth on 18 april 1852. They had a daughter: Christine, born 1856. William, died at Latheron, Caithness in 1878. According to graveyard inscription he is buried in Helmsdale with Janet. Please contact me by email if you can add anything to this or if I can help further.
