Looking to return Silver Star to family

A friend of mine found a Silver Star certificate for a Colonel Donovan Swanton. It was issued "For Gallantry In Action, Abucay Hacienda, Bataan, 22 January 1942" It is a 2nd Oak Leaf Cluster.
After a little research I found, "Swanton, Donovan Col., Inf Senior Instr., Beach Defense, ll Corps" "Swanton, Donovan, USA, 71 W 12th St. New York, NY".
We would very much like to return this to the family of Colonel Swanton.

Any information is greatly appreciated!
