Hello JC,
I expect you've seen the 1851 census for William Flowerday, Ref HO107/2360 Folio 682, page 39, where William Flowerday is living with his wife, Sarah Elizabeth, and several children, in James Street, Hull.
William says his place of birth is Stalham, which is about 5 miles from Ludham.
I was interested to see that William's marriage to Sarah Elizabeth Shepherd was by licence.
Again, apologies if you've seen this entry - I'm afraid the only witness I can read clearly is Harriet Shepherd -
