There is an Ann Marsh here, is this her daughter?

That one's 12, Anna Maria would only be 9, maybe 8 on census day as she was baptised in November.
This Ann could possibly Ann Marsh d/o Joseph and Matilda bapt in Worth M on 7 Oct 1827.
Although she seems to be in the same household as Hannah Bower 17, Richard Corben 9 and Joseph Corben 6.
I think these are Hannah Bower bapt 18 Apr 1824 d/o Charles and Mary Bower,
Richard Corben Bower (base born) bapt 27 May 1832 s/o Mary Bower widow
Joseph Corben bapt 12 April 1835 s/o Richard and Mary.
Charles Bower married Mary Maria Vincent in 1812
Charles Bower died in 1830 age 39 (b abt 1791)
Richard Corben married Mary Bower in 1833 (record doesn't give her status)
Joseph Marsh married Matilda Bower in 1807 in Langton Matravers.
I haven't found a connection between Charles and Matilda Bower. I was hoping to find baptisms and find they had same parents. But it is looking like this Ann Marsh has more connections with Joseph and Matilda.
