Chisholm/Marsh Families settling in Northern Calif.1880

I am researching the Chisholm's from Nova Scotia, Canada.
I don't have much info. at all on "Chisholm" except
this (?) Chisholm married a Ella/Ellen J. Marsh abt.1886.
Ella was born in Ohio 1861-d.1905, and an only child of Rachel B. Marsh b. 1836 Ohio-d.1914,& Henry Marsh b.1836 Eng-d.1908. Ella & her parents all died in Fort Bragg Calif., Mendocino County
Ella Chisholm had 3 children w/unknown Chisholm, Alexandria b.1888, Abbie b.1890, William b.1895, all 3 children also died in Calif.
When the Marsh's first came to California they were in Redwood Ca.
