A Belmont woman chose the right cruise-mates when they boarded the RMS Titanic, which sailed 100 years ago this week.

Caroline Lamson Brown survived her trip on the ill-fated ship thanks to a friend she made on board. She married John Brown, the son of publisher James Brown (a partner in the publishing firm that became Little, Brown and Co.). She is buried next to her husband in the Brown family section of the Mount Auburn Cemetery.

She is one of seven Titanic passengers buried in the Watertown cemetery.

Lamson Brown lived in Belmont for many years, where she was involved with church and civic duties, said Stephanie Messina, External Affairs Department Assistant at the cemetery. Later, she moved to Acton to live on a farm. She died in Concord in 1928 at the age of 75.

Lamson Brown made the trip to England without her husband and children. The journey was made for a sad occasion, a family funeral, and she was accompanied by one of her sisters.

On the ship the sisters made friends with Edith Corse Evans and Col. Archibald Gracie, who took it upon himself to look after the group women traveling by themselves, Messina said.

When trouble started on the Titanic, Col. Gracie ushered the women to the deck and guided them to the lifeboats, which were filling up fast.

“In the chaos she lost her sister,” Messina said. “She and Edith found the last lifeboat, and they would only take one of the women. Edith turned to Caroline and said, ‘You have children, you go.’”

Lamsom Brown made it to the Carpathia, which had picked up hundreds of Titanic passengers, including her sister. Edith, however, was never seen again.
