1881 is even more interesting. They are listed under the name "Umbrella", e.g. Fred Umbrella, Sarah Umbrella etc.
Fred Umbrella 27
Sarah Umbrella 26
John Umbrella 10
Susan Umbrella 8
Joseph Umbrella 7
Fred Umbrella 6
Kate Umbrella 3
Polley Stone 1
Don't know who Susan is (think she's too young to be Sarah's daughter Sarah), but I feel like the child listed below her might be the Joseph Livermore who married Matilda Stone. I used to wonder why his birth is listed on another census as being in Sittingbourne but comments above explaining the family's hop-picking travels explain that nicely.
