Col. Tucker, who also took over the Loughlin factory site and converted it to the manufacture of wooden bicycle rims, became very wealthy. The subsequent owners did not fare quite as well, and the Castle was passed from family to family. Stanley Bryan, the proprietor of the Venice Chocolate Company, owned it in the 1920's. Local physician Dr. Austin Edwards lived there eight years until his death in 1943. Army Major Charles Price owned the Castle until 1949, and it was used as a nursing home by the Morris family in the 1950's.

Bonnyconnellan survived 113 years of various owners, some perhaps indifferent to her needs, but she could not survive the plan of her current owners to carve her up and sell her part by part. Gone are the hand-tooled leather panels in the den. Only cold plaster walls remain. The richly appointed wooden panels of oak and walnut have been cut away and sold. The impressive wooden ceiling beams are gone.
