I have several Highton dentists in my family.Would anyone know what "L.D.S." means after their name?I have a picture of a tombstone at the Southport Cemetery of "Richard Highton, L.D.S."Would that stand for "Licensed Dental Surgeon" or something like that?I also have an ordinance map of the Southport area from 1909.It has dentists names with the "L.D.S", after their name. One even has "L.D.S. R.C.S. ED." Anyone have any thoughts on this?Thanks very much!
