OK I am working on logic here
1786 Richard Angwin m Jane Treveal St Buryan
1787 Jane
1788 Richard
1790 William
1792 George
1788 Richard Angwin m Honour Chirgwin Madron
1788 Richard
1789 Honour
1799 Ann
1792 John
1797 Alice
The second Richard has a mother and sister called Honour, so it is logical that he would call a daughter Honour.
Richard and Elizabeth who married 1811 had four children it would seem as there are three with Elizabeth in the 1841 census - Richard, Margaret and John and Honour is married to a Mr Griffiths and has her own daughter Elizabeth.
Does this help ?
