Mary Lu Brotherton, 80, Watertown

WATERTOWN, NY —  Mary Lu (Osier) Brotherton, 80, of Watertown passed away Sunday afternoon, Aug. 8, 2021, at Samaritan Medical Center.

She was born in Watertown on Feb. 9, 1941, daughter of Charles B. and Helen L. (Keruskie) Osier. She attended Watertown schools, General Brown High School and Mohawk Valley College, where she received a degree in cosmetology.

She was married to Charles Brotherton for over 20 years.

Mary Lu worked for two decades at Joann Fabrics in Watertown, retiring as a manager. She was very active with her children’s activities, serving as a Den Mother for the Boy Scouts and as a Troop Leader for the Brownies. She was an avid seamstress. She enjoyed making costumes for Halloween and clothes for her children.

As the classroom mother, she made piñatas and baked goods for holidays and special occasions. She also enjoyed reading and bowling. While married, she loved traveling with her children and her husband, who served in the US Air Force.

Mary Lu will be dearly missed by those who knew her. She was a loving soul with a heart of gold, who always had a kind word for everyone. We will miss her infectious laughter, but we take comfort in knowing she is reunited with her parents and her beloved dachshund, “PJ”.

Mary Lu is survived by her son and his wife, Jeffery C. and Debra Brotherton, Murrieta, CA; daughter, Michelle R. Brotherton and her significant other Matthew Butler, Durham, NC; two grandchildren, Jackie and Charlie Brotherton; two brothers and one sister-in-law, Robert G. Osier, Watertown and Gary C. and Pam Osier, Waddell, AZ; and several nieces, nephews, and cousins.

Calling hours will be held 11 am. to 1 p.m. Friday, Aug. 13, 2021, at Cummings Funeral Service, Inc., Watertown, immediately followed by a funeral service. Burial will follow in North Watertown Cemetery.
