Looking for the descendents of Henry B. Collins...his sons who lived in Ca in 1899 were:

Amos in Jenny Lind Ca
Anderson, possibly Henry A. Collins,
Spencer, Calaveras Co
Robert Bruce

I had these names but no locations in a gedcom given to me by another family researcher, but she did not know where the sons of henry went...i have found that info and am looking to trade info with other descendents...my ancestor was Alvin Collins who was the oldest child of Henry Bennett Collins i have dates and other info that i am willing to share on these and other family members...
does anyone have census info on these men and their families in 1900 thank you.
