Katy Lynn Guerin died peacefully on June 30. She was 66.

She was a loving mom, grandmother, wife and sister. She had a kind and thoughtful spirit, lived a full life and cared deeply for her friends and family. She will be deeply missed.

Katy was born on Dec. 8, 1955, the youngest of the two daughters of the late Richard F. and Felice Hunter Kleine. She grew up in Park Ridge, N.J. She was small in stature and her family nicknamed her Mouse; however, she had a big, spirited personality.

After high school she moved to Philadelphia to attend Temple University. She was introduced to her husband Joe by his sister, her friend Joan. She and Joe fell in love and married onboard an antique sailboat in July 1979, starting their life together and sharing their love of the water. A year later, they moved to Martha’s Vineyard to begin work and start their family. Together, Katy and Joe grew the family plumbing and heating business on-Island while also raising three daughters.

Her daughters Morgan, Lark and Hannah were the center of her life. She was immensely proud of them and all of their accomplishments. She was their fiercest advocate, especially for Hannah, the youngest, whom she regularly fought for to overcome her learning disabilities at a time were they were not commonly understood. She shaped many of her daughter’s fondest memories through experiences including selling cut flowers, sailing on Go Cat Go, family walks to Edgartown Great Pond, digging for clams in Katama Bay, family ski trips and much more.

Her older sister Patty always looked out for her. As adults the sisters remained best friends and had many adventures together. There were the frequent road trips, often to go apple picking or just to explore. For Katy’s 50th birthday, Joe sent the two sisters to Holland to attend the Tulip Festival.

She was a beloved and adoring Ama to her grandchildren Carter, Rowen, Bowdoin, Hopper and Willa. She also loved her grandpups Tiller, Wren and Juniper.

She was a passionate and knowledgeable gardener. She loved to share her knowledge and passion with friends and family alike.

Katy was predeceased by her husband Joe, who died in 2018.

A private celebration of life will be held in the near future. Her family asks that, on that day, you take a moment to stop and enjoy a flower in nature.
