Katelyn E. Harrington

July 29, 1994 — December 11, 2022


It is with the deepest sadness that we announce the passing of Katie Harrington, 28, of Manchester, NH. After postpartum medical complications, Katie passed on Sunday, December 11th.  Prior to her unexpected passing, she delivered a beautiful baby boy, who is healthy at home with his family.

Katie is the daughter of Dan Bergeron and Diane Morrissette and their spouses Doreen Bergeron and Scott Morrissette. Katie graduated from Manchester Central High School in 2012, and then graduated from Southern New Hampshire University before working at CMG Home Loans. Katie grew up in the mortgage world sitting at the reception desk acting as the President of Regency Mortgage from the time she was 3 years old.

Katie was an amazing, selfless, young woman who shined a light so bright she lit up everybody’s world. Her love of friends and family filled her calendar with constant check-ins, encouragement, and advice. She was a wonderful daughter, a caring sister, devoted and loving wife, and ready to be the perfect mom to her son Weston James.

Katie loved taking photos with her family and friends and created an amazing photo story that will live on with us forever. She taught us to love harder and not take one moment for granted. 

Katie is survived by her husband Sean Harrington, and her newborn son Weston Harrington; her parents; her siblings, Jackson Morrissette, Savannah and Cameron Bergeron, and a multitude of grandparents, aunts, uncles and cousins.

Please join us to celebrate Katie’s life on Monday, December 19th from 4 – 8 pm at the DoubleTree by Hilton Manchester Downtown Armory Conference Center.  700 Elm Street, Manchester, NH.  Katie would enjoy a casual environment filled with ugly Christmas sweaters.

In lieu of flowers, please consider a donation to support Sean and Weston.   Fundraiser by Sara Reed : Support Sean & Baby Weston - In Memory of Katie (
