Mary Call Darby Collins was the last of Call's descendants to own The Grove. During LeRoy Collins' tenure as governor, The Grove served as the unofficial executive residence while the current Florida Governor's Mansion was under construction, from 1955 to 1957. The Collins family owned The Grove until 1985, when the state of Florida acquired the property for the purpose of creating a state historic house museum. The Collins family received life leases and lived there until their deaths. Following the death of Mrs. Collins in 2009, the property formally reverted to the state. The property includes a small active family cemetery that predates the current Grove residence and serves as the final resting place for several generations of the Call and Collins families.
