Conklin or Theodore

Lawrence Montgomery’s middle name has always been something of a mystery. Most of his official documents appear to have “Theodore,” and he often went by “L.T.,” but many family letters instead addressed him as “Lawrence Conklin” or “L.C.” I had always thought he wasn’t sure what his official middle name was, but Rinda Montgomery Conwell remembers being told that his real middle name was Conklin, but Grandpa didn’t like it and changed it himself. Can anyone else shed light on this mystery? Let us know!
