Thank you for your reply.
I would be grateful for any information from your grandfather.
I have discovered that 7 of Henry Guichards children died in infancy or childhood. The only death certificate I have seen gives his daughter Ann's death in 1860 as exhaustian from burns. She was 10 years old. It's possible that they might have had a house fire which may explain him going to the workhouse or it may just be an accident.
