The body of an 8-year-old grandson of former Lt. Gov. Kathleen Kennedy Townsend of Maryland who went missing with his mother in a canoe last week was recovered in the Chesapeake Bay on Wednesday, two days after his mother’s body was found, the authorities said.
The Maryland Natural Resources Police said that the body of the grandson, Gideon McKean, was found 2,000 feet from where the body of his mother, Maeve Kennedy Townsend McKean, a granddaughter of Robert F. Kennedy, was recovered on Monday.
Gideon’s body was found in 25 feet of water, over two miles south of his grandmother’s home in Shady Side, Md., south of Annapolis, the police said.
The two disappeared Thursday afternoon after Ms. McKean and Gideon set off in a canoe from that property to recover a ball and drifted into the bay, according to the family and the police.
“They got into a canoe, intending simply to retrieve the ball, and somehow got pushed by wind or tide into the open bay,” David McKean, Gideon’s father and Ms. McKean’s husband, explained in a Facebook post on Friday.
A concerned citizen noticed the mother and son drifting away in the canoe and called 911 around 4:30 p.m., according to the Anne Arundel County Fire Department.
“After that last sighting, they were not seen again,” Mr. McKean said.
There were up to three-foot waves and 29-mile-per-hour winds in the bay when the mother and son disappeared, according to the Coast Guard.
In a Twitter post on Wednesday, Gov. Larry Hogan of Maryland asked the public to continue to support the family.
“Please continue to keep their family in your prayers as they mourn this devastating loss,” he said.
In a statement on Wednesday, Ms. Townsend, the former lieutenant governor, thanked Governor Hogan, the Department of Natural Resources and the police.
“They have helped us bring some closure to this terrible loss, and our family will always be grateful for their tireless work,” she said.
On Monday, in a video, Representative Joseph P. Kennedy III of Massachusetts remembered his cousin, Ms. McKean, as “an extraordinary mom.”
“Maeve was my cousin closest in age who I looked up to,” Mr. Kennedy said, adding that she was “an incredibly vibrant young woman.”
Ms. McKean was the executive director of the Georgetown University Global Health Initiative and a Peace Corps volunteer. She served on the board of the Brady Campaign and the Robert F. Kennedy Human Rights organization, Ms. Townsend said on Friday.
“Our Maeve devoted her life to helping society’s most vulnerable,” she said.
Mr. McKean and Ms. McKean had three children: Gideon, Gabriella and Toby. In his Facebook post, Mr. McKean said that his wife was his soul mate and called his son compassionate and brave.
“I used to marvel at him as a toddler and worry that he was too perfect to exist in this world,” Mr. McKean said. “It seems to me now that he was.”
