The feeling of loss over the lives taken in the Oso landslide hit home on Whidbey Island.

And residents on the island are rallying to help.

A benefit concert is planned for Friday night, April 4, at the Roller Barn in Oak Harbor to help Seth Jefferds, an Oso resident who lost his wife and granddaughter during the March 22 mudslide.

Jefferds is the brother of Whidbey residents Ian and Rawle Jefferds, co-owners of Coupeville-based Penn Cove Shellfish.

Seth Jefferds’ wife Christina Jefferds and their 4-month-old granddaughter Sanoah Huestis were in the Jefferds’ Oso home along the Stillaguamish River when the slide struck.

“He lost his house, his wife and grandchild,” said his sister-in-law Karen Jefferds, Ian’s wife. “He’s not the only one certainly. We’re trying to do everything we can to help him rebuild his life,” she said.

“A lot of people wanted to be involved to help generate money for him.”

Whidbey-based band Johnny Bulldog will perform the benefit concert, with doors opening at 6:30 p.m. and music starting at 7:30 p.m. Tickets are $50.

The use of the Roller Barn is being donated for the event, as is pizza from Hot Rocks Pizza and beer from Flyers Restaurant and Brewery.

Tickets are being sold at Flyers, Re/Max Acorn Properties and Ace Hardware in Oak Harbor and bayleaf, the Front Street Grill and Red Apple Market in Coupeville.

Seth Jefferds, a volunteer firefighter in Oso, and his stepdaughter Natasha Huestis had gone to town when the mudslide occurred. It took nearly a week until searchers found the bodies of their loved ones.

Christina Jefferds, 45, was a dental office manager in Marysville known for her gentle-heartedness.

“She was a great person,” Karen Jefferds said Monday.

“I guess like anybody, we’re all in mourning. We’re dealing with it the best we can.”
