I recently located precious and previously lost info on my Dapp family connections...one is a newspaper clipping dated Feb.24,1931...with a photo of Edward Dapp(husband of Mame
SPROW)here is an exerpt of this article..."The Byrd Expedition to the South Pole used 25 message parachutes,invented by Edward Dapp of 1938 North Third Street...The parachutes were made by Mrs.Dapp at home before the factory was established at 1005 North Sixth Street."
I also have a copy of Edwards' patent certificate for these parachutes dated 1929.
Also a will naming Stewart Dapps' niece in 1977 ...Anna Mae COOK of Harrisburg Pa.
I hope this bit of information will help me to connect with some other Dapp families.Please email me at email@example.com
