Dover, NH: Kathleen J. Marshall, 58, of Dover, NH passed away peacefully from metastatic breast cancer on Saturday, February 16 at Wentworth Douglass Hospital with her family and several very close friends by her side. Kathy was born on February 13, 1961 in Salem, Massachusetts; the daughter of Ronald B. and Janice M. (Cyr) Marshall. Kathy was a loving daughter, sister, friend and aunt. She was a fierce advocate for those most vulnerable – working for more than 10 years as a case manager for individuals with developmental disabilities and before that on behalf of children through Child Protective Services in Maine. If not walking in the woods, Kathy could be found cheering on the Patriots, engaged in political debates, and spending time with family and friends. She especially loved camping in the White Mountains under the moon and stars. Kathy is survived by her father, sister and best friend, Lynne; sister, Tracy, brother-in-law Mike and adored nephew Nash; puppy Jackson, a host of cousins, and many dear good friends. A creative, sweet and loving spirit, Kath will be fondly remembered and missed by all. She is pre-deceased by and now united with her mother, Janice. In lieu of flowers, donations may be made in honor of Kathy to the Upper Saco Valley Land Trust https://www.usvlt.org/donate or the Seacoast Science Center https://www.seacoastsciencecenter.org/#. Family and Friends are invited to a memorial service for Kathy on Saturday, May 4, 2019 from 11:00am at St. Georges Episcopal Church, 407 York Street, York Harbor, Maine. A private Interment will be held in the late spring at Puritan Lawn, Peabody Massachusetts. To sign our online guestbook, please go to www.purdyfuneralservice.com
