Hi to all interested in Christopher Adams Parker, defender of the Alamo.
Christopher's sister married Gen. Edward SPARROW, not SWALLOW of Louisiana.
Also the Texas State Historical Society lists C.A. Parker as being a descendant of the Sparrow family, but that's NOT possible seeing as the Sparrow connection came thru his only surviving sister Minerva, marrying Edward Sparrow at Trinity Episcopal Church in Natchez.
Records of his grandfather James Armstrong, Sr.'s Revolutionary War involvment can be found at Ancestory.com. Christopher's uncle, Commodore James Armstrong, Jr., was a noted Union naval commander and helped open trade with China.
