IGI has Agnes Lawton married to Jos. Musworth 21st May 1866.
An Agnes Lawton was born 1842 to James Lawton and Margaret Kneal at Lonan.
Another was christened 1844 to Thomas Lawton and Nessy Cowin at Lezayre. It is this one I suspect married Joseph Unsworth and moved to Atherton in Lancashire.
Nessy, sometimes referred to as Hessy by IGI, was christened and married in Braddan.
Another child was christened Louisa and this name can be found in the 1881 census a few doors away from Agnes in Atherton .
