LAURA JANE GRACE DICKEY is buried next to her husband HENRY J. DICKEY that the REST LAWN MEMORIAL PARK Cemetery at Junction City, Oregon which is north of Eugene, Oregon.
I haven't actually seen to headstones.This information was obtained from some very old books cemetery survey books at the local public library.
I may be able to obtain photos of the Pioneer Cemetery burials, but not probably not the J.C. one.Maybe there is another kind soul out there who could check out the Junction City cemetery.
I also have a MARY A. DENNISON who married ABRAHAM D. CANNON in Lane County in 1878 - Any connection to your DENNISON?
