Ah Jane I should really read all emails before replying!
I mentioned first wife Elizabeth Park but not sure where that came from.
I have Laurence down as born 1853 and as Robert married again that year maybe it wasn't a divorce but death Elizabeth dying during child birth?
Question is who took care of my great grandfather! Doesn't look as though was Margaret.
Yes Robert was a master mariner if send me your email I can send you a copy of the sea faring Charnley's based on Alan Lockett's articles.
