Margaret (Peggy) O'Drain lives in Richmond, California, and a retired State employee. She was a longtime tour guide and volunteer with Mare Island Historic Park Foundation. Discovery of the aging, neglected cemetery at Mare Island offered the perfect opportunity to combine a life-long interest in all things historical with an undeniable attraction to old burial grounds. Her goal is to preserve a place in history for Mare Island, with stories of those who will forever remain on Mare Island. Joyce Giles (co-author) lives in Vallejo, California, a former employee of Mare Island Naval Shipyard, and long time volunteer with Mare Island Historic Park Foundation as tour guide, docent, and manager of Mare Island Museum. She assisted Peggy in the first publication about the cemetery and after several years of seeing the cemetery in neglected stage, wanted to update the previous publication to include Section A (officer burials), and also an afterward showing the rebirth with new irrigation, fencing, cleaned tombstones, and clean up after the fires of 2019, and also an index.
