Hi I am a relative of Maria Everest/Parrott/Rhoades/Quinn - Maria had three husbands the last being James Quinn. Maria Rhoades married James Quinn, age 49, on March 23, 1863, in Marion County, Oregon. He applied for citizenship in April 1871. Nothing more is known of him; he was not listed with Maria Quinn and her family in the 1880 census.
I found that information on Find a grave. I would say that given that her birth father died in 1857 and her mothers second husband left town, that it could be the reason she gave James as her father's name.
My Great, great grandfather was her brother James Everest that married Eliza Churchman.
