Greetings Zoe,
I was able to get to the National Library sooner than I thought.
The only Margaret FEIST I found was born in 1856. I started at 1864 and worked back. Now this ties in with the thoughts Andrea had.
Margaret FEIST Horsham 2b 242 Dec qtr 1856.
Interesting how things go I just found my FEISTs were in Horsham also.The first pick up for me was a marr. of James FEIST to Elizabeth BOTTLING in 1779. Have not been able to find his parents as yet.
I do hope Margaret was fibbing about her age

Cheers
Kaye
