Thank you for your reply concerning Oliver (R) LInthicum, son of John Thomas LInthicum who married Martina Hayden. I had always assumed that my ORL was born in Balto city or Co as it is such a hotbed of Linthicums.he died there july26 1944.This was an interesting man who, although suffering from life-long alcoholism worked with Thomas EDison. This is confirmed but I do not know details. Would love to hear more of what you have. Thanks again, Ann Watson P.S. He was my great grandfather and married Mary Catherin Glenn of Balto.
