On 1881 census: Walter and Florence WEAVER are living with Amelia GILES who was born in Cofton Hackett in 1836/37.
Rachael WEAVER, a widowed niece aged 38 and born in Bromsgrove, is a domestic nurse for Denham and Emma BAKER who have a young baby in Aston. This Rachel may be Amelia's daughter who married John WEAVER.
Coincidentally(?) Emma BAKER is also born in Cofton Hackett in 1817/18. So WEAVER, Bromsgrove and Cofton Hackett link the two records - also Rachel's age is correct and her status is an explanation as to why Rachel's husband John WEAVER is missing from the 1881. John Henry WEAVER probably died young.
If Rachel WEAVER nee GILES is Denham BAKER's niece then Denham BAKER's sister married WILLIAM GILES. So Amelia GILES could be Amelia BAKER.
