They came from across Jamaica Plain and nearby neighborhoods, about 100 grandparents, moms and dads, children and babies, with roots in Africa, Asia, Europe, and the Americas.

With dogs straining at leashes and kids rumbling along in strollers, on vibrantly hued bicycles and, in the case of 5-year-old Brendan Bailey, a wooden-slatted wagon, the throng circled Jamaica Pond on Thursday morning as one, after months that strained bonds of family and community.

“I figured Thanksgiving would be tough for a lot of people this year,’’ said Erin Ryerson, 34, who organized the “solidarity stroll.’’

Standing with her husband, Hal; baby, ­Loretta; and French mastiff, Judah; Ryerson became emotional describing the recent election. “I was crushed,’’ the West Roxbury resident said. “This was definitely born out of a need to do something, anything.’’

To Kai and Sarah Johnson, the day was a chance to teach their daughters, Isla, ­Emmaline, and Bella, the value of inclusion by joining with neighbors of all backgrounds.

“It’s exactly why we live in this area,’’ Kai Johnson, 31, said of the gathering’s diversity. “It’s JP, and that’s part of the strength of this community.’’

Six-year-old Isla said she has Muslim and immigrant friends at the nearby Curley School.

“There are a lot of people who are scared of Donald Trump in my class, including the teachers,’’ she said. “We’re showing people that . . . we still care for our city.’’

The crowd completed its circle of the pond around 10 a.m., gathering beside the boathouse to sing John Lennon’s “Imagine’’ as a light sleet began to fall. Before leaving to prepare their holiday feasts, they shook hands, hugged, and laughed together, as a community.
