Hi Bryanc,
On the partial (not up todate) birth registration index there is only one Henrietta Ashwell year 1863 district Biggleswade, county Bedfordshire/Hertfordshire.
The 1871 census shows this Henrietta Ashwell born abt 1874, POB Hatch Bedfordshire, parents Charles and Sarah plus loads of siblings.
On the 1881 census her POB is given as Brookend Bedfordshire and is living in Morley, Yorkshire with parents. There is another Henrietta Ashwell born Malta British subject, but she appears on the 1891 census with her parents.
You will need to get Henrietta and Charles marriage certificate, which will give fathers names and occupation, plus age of bride and groom and family address.
Henrietta Durrant's death was registered in 1890.
