TRIPTREE/DAVIS families

[Aileen18]

Looking for information on Elizabeth Triptree b 1787 in Yeovilton Somerset and William Davis b 1785 in Yeovilton, Somerset married 1805 in Yeovil Somerset. I have found Elizabeth in the 1851 Census est age 64.  She is living with Mary Triptree who could possibly be her sister - listed as a lodger aged 62.  Also listed on the census are
Elizabeth Davis -21
George Davis 33
Harriet Davis 27
Felix Ridvert -23

I wonder if Elizabeth, George & Harriet are William & Elizabeth's children. 
Elizabeth/William are my ggg-grandparents.
Any help would be appreciated.
