From looking at the 1841-1861 census, it appears there were several families with this surname. I'm trying to find out more about Martha Darrington, born 1827 in Bedfordshire. There is a Martha Darrington in the IGI, baptized 1827 in Roxton. Only a mother listed, that being Mary Darrington. I don't know if this means Martha was born out of wedlock. I also found a court record on a Martha Darrington, correct age, who was found guilty of stealing shoes in 1843. She got six months hard labor.

The Martha I seek married John Crow(e) about 1852, although I've found no marriage record. Their oldest child, George Crowe, was born in 1852. The family moved twice in the 1860s, first to Herefordshire and then to Shropshire.

I found a record at the UK archives that MAY be related to Martha's mother, Mary Darrington. "EATON SOCON PARISH RECORDS: Samuel Darrington 7yrs, George 7yrs, Sarah 6yrs. Roxton, Beds.
