I will try to give you what I have found up to now there are two birth dates listed for Alice Richardson 1815 and 1817
in 1851 census Alice is a mariner's widow living at Victoria Place South Shields also with her are her nephew Charles Brampton aged 15 b Middlesex and his sister Alice aged 9 Middlesex
In 1861 Alice is with the Mitford family aged 46 yrs down as a visitor
1871 I have picked her up with Jacob Black she is aged 56 yrs down as his cousin( now he is a relative of mine and I have most of his records ) Jacob was b 1837 at Earsdon Northumberland he is head of the house a railway clerk aged 34
1881 Alice and Jacob are still together now living at Coxlodge he is still a railway clerk aged 44 Alice down as a 2nd cousin aged 63 also now they have another relative Sarah A Allen aged 15 born Southall Middlesex London ( I think she is the illegitimate daughter of an Elizabeth Allen not sure )
1891 They are still living at Coxlodge I think this is near Gosforth not really looked for it Alice is 74 down as a relative also Sarah A Allen is still with them aged 25 down as a relative born Middlesex London
Jacob is retired living on his own means aged 54
In 1892 I find a death for a Alice Richardson Castle Ward not sure think this could be Morpeth) aged 75 born Felton 1817
What I cannot find about Alice her marriage to

1901 census I find both Jacob a retired railway clerk and Sarah living at Frome Somersetshire she is down as a house keeper aged 35
1911 they are still at Frome Somerset
1913 I found a death ( think its my Jacob ) aged 77 Morpeth Northumberland
