Those of Lambert Junior's daughters that I know about were Anne Moir Hepting, named after her maternal grandmother Anne Moir (about whom I have a fair bit of information); Dorothy Mary Hepting (married name Mitchell) and Rhoda Alexander Hepting.

I met Dorothy Mitchell in 1971 on my first visit to Scotland, that was a few years before she died. I'm almost sure that she had no children, or rather, surviving children, not did Rhoda, who never married. I don't know about Anne Moir Hepting, but I could look for a marriage next time I'm at the Scotland's People Centre, if you haven't heard from anyone else by then.

Best wishes for your research.
