NEW BEDFORD — The Rotch-Jones-Duff House and Garden Museum will hold its annual garden party on Saturday, June 15, at 6 p.m. This year’s fundraiser carries the theme, “Keeping Up With The Duffs,” celebrating the era of the Duff residency at the house and a mid-century chic vibe. The evening features live piano music, DJ, catering by The Westporter, open bar, and a silent auction. Honorary co-chairs of the event are Deborah Pierce and Carlotta McKee, both granddaughters of Mark and Beatrice Duff, the last residents of 396 County before it became a museum.

There will be more than 50 items up for bidding at the silent auction including gift cards to local restaurants, wine, exercise sessions, antiques, travel packages, and garden items.

Serving more than 2,000 area students annually, curriculum-supporting programs are offered free of charge to New Bedford students. Programs at the Museum help students engage in critical thinking, learn about the community in which they live, and make connections between the past and present. The Museum’s public education programs, many of which are free, range in topics, from transcendentalism to topiaries, and serve about 1,300 people each year.
