I think I need some help from members familiar with US sources.
The question is did Mary Ann emigrate to New York alone prior to 1877 marriage ?
or did the whole family go to New York ?
Accessed via FamilySearch :
Mary Anne Payne ; father John Payne; mother Sarah Downes ; marries James Herbert 3 Jun 1877 Manhattan, New York, US
original source New York Marriages 1686-1980.
I think this event could match with Mary Anne Payne 1851 Tiverton ; father John Payne 1811 ; mother 1820 Sarah Down ; married 1842
with other children William Payne 1842; Elizabeth Payne 1846; Sarah Payne 1848 as per 1851 Census Cullompton
http://search.findmypast.co.uk/record?id=GBC/1851/4355417/00458&parentid=GBC/1851/0009165944Although Mary Ann's birth appears to be registered as Mary Ann Pain 1850 Tiverton Quarter 4 Vol 10 Page 259 mother's name Down.
I have found the family in Poplar, Middlesex in 1861.
Class: RG 9/301/169 p11
But there are so many possibilities once all the children become adults in London. I don't think they are there.
thanks
