Hi there, you are quick! ok it is looking like this Anna who passed in 1886 is my ggg grandmother. I have a John Hill who wife was unknown. His son Joseph Robinson Hill is my gg grandfather, only the father was known thru marriage details and yes you were on the right track with his marriage to Mary Prosser. So it seems that William and Robert were brothers to my Joseph, perhaps the inscription re Frederick Louis Hill "nephew of the above" refers to the first inscription of William as he was his nephew through William's brother Joseph. Now if this is correct Anna's DOB is approx 1817 and she had the known boys in her 20's. Do you have record of any more children. I have not yet figured the other Anna Susan yet but I am digging deep in my records for her now.Thanks heaps, my elderly mother is loving this!
