Found my great-great-grandfather by a few clues. Related to Oliver Lodge the physicist, wife's name Katharine, profession: surgeon, served in the U.S. Civil War, a daughter born in New York. This found over years in various web sites. The clincher for me was a small packet from NARA with a handwritten letter from Katharine requesting a widow's pension outlining some details about her husband Charles Lodge which matched other details. My hands shook as I read the letter in her hand. A man whose name or story I never heard was brought to life. I found more and more, about his family and relatives.
Now I am trying to find his grandchildren by his daughter Geraldine under Baker-thats harder than Lodge!
