Snr married Sarah. Snr was Rev Dr Richard Turner LLD, Jnr was Rev Richard Turner, but he refers to himself as Dr & LLD in his will althought here is no eveidence he was entitled to those honours. Jnr wrote several books, early editions have him simply as Rev. Later, after his death, and perhaps confsuion because both were authors, the titles become confused. Also both went to Magdalen.
