[8][4] The first Pebble Beach Championship for Women was played February 9–12, 1923, with Hollins as champion over defeated Doreen Kavanaugh in the final match.

Seth Raynor routed Cypress Point but died before it was built; she was ultimately the reason Bobby Jones hired MacKenzie to design Augusta National Golf Club.

[12] In 1927, Hollins bought 2,000 acres (810 ha) in Carmel Valley from Morse's Del Monte Properties, where she entertained guests such as Sir Montagu Allan, his wife, and daughter from Montreal, Canada.

[13] In 1936, she sold 1,000 acres (400 ha) of her ranch to real estate developer Frank B. Porter Hollins for $32,000 (equivalent to $702,619 in 2023).

[14][15] "Of all the wealthy and privileged friends around the world she'd treated with such generosity and warmth throughout her life, only her former employer at Pebble Beach, Samuel Morse, stepped forward to help.

He saw to it that Marion was moved back to Pebble Beach and gave her a house rent-free, and a face-saving title, with no actual responsibilities, at his Del Monte Corporation."

[1] Hollins was inducted posthumously into the Suffolk Sports Hall of Fame on Long Island in the Golf and Historic Recognition Categories with the Class of 2002.
