Hi Rol. In answer to your question, no I do not have baptism dates for either George or Frederick. Only that Frederick was born 1814 in Plymouth Devon and as for George I am assuming that he is a brother of Frederick as he was a carpenter or Joiner like the rest of them. Frederick was also a carpenter/joiner and it was stated in his probate that he was an acting Engineer in the Royal Engineer Department of Her Majesty's War Office and he was in Sierra Leone on the West Coast of Africa. His wife is named as Mary Burgoyne of No. 73 Coburgh Street Plymouth widow.
I have not been able to find a census on this family for 1851, however, when in Plymouth about 20 years ago I tried to look at the fiche of these census and it was impossible to read. In the 1861 census, they are down as Mary Burgoine, William, Charles and Edward Burgoine and a niece Anna ( which I think is Hannah Burgoyne) this census address was Coburgh Street Plymouth. Hannah later married George H Jenkins an artist and Landscape Artist and they lived in Plymouth.
The William referred to in the 1861 census is actually Frederick William my g grandfather. In about 1992 we had a Mrs Guthrig of Plympton Plymouth do some research on our family and she was the one who found the birth date for Frederick and who his parents were. I will look forther in my reams of paper to see if I have any information on George or any other members of the family for that matter.
