Nancy P. (Crear) Harrison Bush, age 69, passed away Thursday, May 27, 2010 after a one-year battle with brain cancer. She was born, February 13, 1941 in Boston, the daughter of the late John J. and Constance (Amori) Crear. She graduated from the former Howe High School in Billerica. She worked for Raytheon and Bedford Engineering early in her career. She worked until her retirement 10 years ago from DuPont & Bristol Meyers Squibb. She planned her retirement very strategically and was very excited about her future. She devoted much of her time and energy to her family and, as a caregiver, to spending the last 10 years taking care of her mother, who recently passed away. Her true happiness came from spending time with her five children and grandchildren. She was extremely talented and enjoyed sewing, flower arranging, picture taking, and knitting. She is survived by her children, Pamela H. and James Lelacheur and Bruce P. and France Harrison, all of Hudson, NH, Paula A. and Edwin R. Derby III of Tyngsboro, MA, Glenn P. Harrison of Derry, NH, and Natalie M. Bush of Billerica, her most cherished grandchildren, Michael J. LeLacheur, Emily M. Harrison, Elizabeth A. Derby, and Edwin R. Derby IV. She is also survived by her five brothers, Richard, James, Chris, Dave, and Brent Crear. She leaves her dearest friends, Maggie and Eileen. She was predeceased by her beloved granddaughter, Christine A. Park.
