Reply (received this morning) from Derbyshire Family Hist. Society:
"Your research request and payment was received last week, thank you. It would appear that you are looking for birth, marriage and death details for Harriett, Alice and John Fisher. We are assuming that you have found them on the census and also a possible marriage to James Hall. The marriage we have found for Harriett Fisher to a James Hall is in 1896. If this were correct then the children would have the surname of Hall.
We are not sure what information you have already but think that you have found them in 1911, all in the workhouse. Harriett is single born Ilkeston and she has two illegitimate children, Alice and John. In 1901 Harriet, single, is with Alice again in the workhouse. 1891 she is with her widowed father, George and in 1881 she is with parents, George and Harriett.
There is no baptism record for Harriet in Ilkeston. There are two marriages for a Harriett Fisher after 1911 but the only way to know if either are her is to buy certificates. One is in 1916 Ilkeston St Mary to a Joseph Stenson and the other in 1924 Cotmanhay to a Thomas Gerrard.
I take it that either Alice or John are your direct ancestor. Do you have any other information on them as there are a great number of marriages for these names? Without having an idea of date and place it will be nearly impossible to do. Deaths will also be difficult to find as Fisher is a fairly common name and again could be anywhere in the country and both Harriett and Alice could have married.
Birth certificates will be available for each of them at a cost of £10 each. Harriett Fisher registered Sept qtr 1873 Basford, Alice Fisher, there are two registered Sept qtr 1897 Basford and John Fisher, there are three possibilities, one in Dec qtr 1905 Nottingham and two in Basford Mar qtr 1906. When ordering the ones for John and Alice, you need to state that you would like the mother to be Harriet with no father given and you should not end up with certificates you do not want. We could order the certificates for you but the £27 would not cover the cost of three certificates and research. The search fee of £3 per item, if on our database, would only give a reference leading directly to the certificate. If you would like to send a further £13 we could do the ordering for you."
