On the IGI there is an Elinor Grimshaw c. 3/06/1821 in Kirk Michael. Daughter of William Grimshaw and Catherine Sayle. Could she have shortened her name from Elinor to Ellen?
The IGI also has a marriage of James Holden to Ellen Grimshaw 31/7/1836 in Church? Lancashire.
In the 1881 census they are shop keepers. This may mean that they were static and checking earlier census may prove useful.
