Home of Chaplain Gordon Winslow of the 5th NY Zouaves.  Most likely home to his son Colonel Cleveland Winslow also.  Gordon died while tending the mortally wounded Cleveland on a ship back to Washington where he was pulled into the Potomac River by lowering a bucket for water into it.  Gordon being elderly and frail was sucked in by the River and drowned.
