Well Mike there's quite a bit of information here for you to read through. I've discovered that George Bisgrove & Ann Trott had many other children. Would you like the information on these individuals? I have also found them on the 1841 census which again I'm happy to provide the info for. I don't want to swamp you.
Perhaps you'll let me know if and when you'd like more on this family.
Regarding Henry Richards, Susan's father, I'm not finding anything - yet! Don't give up hope. From Susan's marriage certificiate can you tell me if there is an address for any of them or even the names of the witnesses? Sometimes this can help a great deal.
I will await your response before I go any further but will be glad to persue any of the above.
Best wishes.
