That's all that I found for John and Louisa in FamilySearch and Ancestry.
I'd contact the Honolulu County Genealogical Society, http://honolulucountygenealogicalsociety.blogspot.com/
. They have a tremendous amount of information which isn't listed on their blogspot but was listed when they were on RootsWeb.
Another resource is the Hawai'i State Archives, http://ags.hawaii.gov/archives/
. Successful Searching!
