I'm having trouble finding my g-grandmother Helen Mary Horrell. Here's the information I have about her -

30 June 1884, marriage to Horatio Henry Bethell in Hammersmith, age 25, spinster, father Thomas Edwards Horrell, farmer

1891 census, listed as Ellen Berthell, living with husband Henry and family in St Pancras, age 50, born Northampton, Peterboro

1901 census, listed as Helen Mary, living with husband Henry and family in Tottenham, age 40, born Suffolk, Bury St Edmonds

1911 census, listed as Helen Mary, widow, living in Tottenham, age 50, born Cambridge, Peterboro

10 February 1935, died, age 76 years


From the above dates and places of birth, it would appear likely that Helen Mary was born in Peterboro around 1860 but I cannot find her birth record anywhere.

Does anyone have any good ideas of how I can track her down?

Thanks
Carol
