Hello, I'm trying to trace an Irish family who are present on the 1901 Irish census but have vanished by 1911. They are Robert (42) and Mary Speers (40) of 4 Clarendon Street, Londonderry with children John (17), Robert (15), Caroline (12) and David Benjamin (10). (However, the ages of the parents may be incorrectly entered on the census by as much as 8 years). I can't find the family after this but when Robert and Mary's neice marries in Haverton Hill, Durham, England in 1904 a Caroline Speers has signed the witness box on the marriage certificate which may well be her as I can find no evidence of another Caroline Speers in the area. If this is her, they disappear completely after this. I've had my son put their information into his ancestry account but no joy there either. Is there anyone who can help us find them? It has been suggested to me they might have emigrated but I don't know where to start to find out about that. Can anyone help?
Many thanks,
Judith
