Leonard Ravenhill's father

Does anyone know anything about Leonard Ravenhill's father? I heard in one of his sermons that he was also a preacher.
Thanks

If you watch Leonard's video interview he speaks briefely about his father... his father was a layman who was incredibly changed by the Holy Spirit and would occasionally do street preaching. I don't think Leonard ever elaborates farther than that -he certainly wasn't a circuit rider like David Wilkerson's grandfather.
