Stacy Elizabeth Nickerson-Hall and Stephen Martellucci joyfully announce the engagement of their daughter Katama Marie Martellucci to Janice Ownbey, daughter of Joyce Ownbey and the late Richard Ownbey of Sacramento, Calif.

Katama is the granddaughter of Sonny and Claire Nickerson Hall; the great-granddaughter of the late Howard and Marie Brown Nickerson; and the great-great-granddaughter of the late Capt. St. Clair and Elizabeth Morehouse Brown, all of Edgartown.

Katama Marie, a Vassar College graduate, is the senior instructor in the Garden Apprentice Program at the Brooklyn Botanical Gardens. Janice, a graduate of the University of California at Santa Barbara, is the adventure coordinator for the Appalachian Mountain Club’s Youth Opportunities Program NY/NJ Chapter. Both young women worked as farm-based educators at the Farm Institute at Katama, and they met when they were both working as educator/naturalists at the Exploring New Horizons Outdoor School in Loma Mar, Calif. They now reside in Brooklyn and are planning a 2016 wedding.
