Hello William, John Henry Chunn is the son of Mark B. Chunn of Birch Hanger Manor . The 1850 or 1860 St. Marys County Census does not show a mother. The 1860 Census Shows Mark age 49 farmer, Ann age 19 (maybe 2nd wife) John H. age 21 Elizabeth M. age18 William L. age 16 and Charles age 14. The book Marriages and Deaths In St Marys has an obit. for Mark Bourne Chunn. It says. he died 15, May 1874 age 64, native of Charles Co. Md. but for past 35 years, res of Chaptico Dist. St Marys County. Buried at his home on the 17th. I think he was a judge. John Henry Chunn died on oct. 31, 1905 and is buried at Louden Park Cemetery Baltimore. That's all I can dig up for now. Do you know of any photo's of John Henry? Thanks, Rob
