Following the info. you sent to me I went back to my notes and it sewems to be the same family - although the info from the 1881 census (Cannock) told us that Alfred was born around 1852, which means a difference of about 3 yrs with your dates.His wife and children we have recorded seem to be the same as yours - good news.
Our Sarah Westwood (senior) was born 1815 in Dudley but she was widowed when living with Alfred and Sarah in 1881.The dates make her the same Sarah Westwood that you have with her daughter being born around 1851.
So, all in all, it seems we are on the right track.I have yet to find out more about the family in general including Alfred and his parents etc.On the 1881 census if said that Alfred was from Rugeley and his wife Sarah from Cheslyn Hay.
I live in Staffordshire not far from the Rugeley and Cannock area and my mum who's helping me with this lives just the other side of Lichfield, Staffs.If I get hold of anything interesting I will let you know - it would be great if you could do the same.
Great to swap notes etc. and especially with a relative!! Talk to you soon, Annette.
