Hi Sarajane,
Luckily she didn't move house between the two censuses:
ref HO107 472-19 folio 10 page 14: West Street, Faversham (1841)
Mary Buesden age 35 ind
James Waterman age 30 tailor
William Bailey age 30 woolsorter
all shown as born in county
James Waterman looks like a 'permanent' lodger, as he was still there in 1851. No sign of a husband for Mary I'm afraid.
