[Phoenix]

31st July 1683 and in Holy Trinity Minories:

John Armitage bachelor of St Martin field and Margaret Standish spinster of Allhollowe Barkin maried by Mr Weston.

Mrs Margaret Armetage, her daughter Ann and Frances Standish (her sister) are named in the will of Ellen Sheppard made and proved in March 1702/3:

Frances brought a case in Chancery against Mary Rowe, widow in 1712, presumably because she still held various valuables belonging to the late Ellen Sheppard

but Margaret (and her daughter) seem to have vanished without trace.


A Margaret Armitage, wife of John Armitage from black boy alley Chick Lane was buried in 1708,

Ellen Sheppard was the wife of the rector of Sanderstead - can her legatee really have been reduced so low?


Nor do I know what Margaret was doing in Barking: her father was buried in Croydon only six weeks later, on 16 September 1683:

Does anyone have any bright ideas? I would have hoped for a will, but I cannot see one (though London has far many more courts than are online)
