Hi!
This is the most amazing 'adventure'! I have spent almost all day checking the various references, cross referencing and writing it all down. I have found sites I haven't previously visited thanks to you all!
Kath, thanks for setting that all down that's exactly the conclusion I have just reached but couldn't possibly have spelled it out as you did! Or even got anywhere like this far without your help!
So yes basically Ann Mann was brought up by her Dad's (Robert Fishwick) half sister (Ann Morrison nee Rodgett). Ann Mann's half brother William Mann (b.1854) went to live with the Ross family following Alice's death in 1866.
The only puzzles remaining are 1) I doubt I'll ever trace Robert Fishwick's Dad

and 2) there's a problem with good old Ann or Hannah Fishwick!
On
www.lan-opc.org.uk there are
1) Hannah Fishwick born to Thomas Fishwick and Ann baptised 16.11.1794 living in Charnock Richard.
2) Ann Fishwick born to Thomas Fishwick and Ellen born 7.11.1796 baptised 12.1.1797, living I presume in Chorley. And ... .... wait for it ... ... yet another one
3) Ann Fishwick born to Thomas Fishwick and Ellen born 18.4.1798 baptised 20.5.1798, again living in Chorley!
I can't locate a burial for the first of Thomas and Ellen's girls.
Also both Robert Fishwick b. 1822 and James Fishwick b. 1818, who would seem to be brothers from the census info as they are both sons, have mothers Hannah and Ann respectively!
This family is truly doing my head in!!
Thanks Kath and Mo for all your research and everyone else who has chipped in. My Dad will be chuffed to bits when I tell him about his Grandmothers early life. Whether or not he wil believe me is another matter!
Thank you so much,
Lyn
