I've been using Ancestry but there seems to be some census information missing for 1901 (or I can't find it!).
Name: Maria Coyle 1863-1937, married to Peter Coyle 1861-1901; he died in 1901 so may not be in the census.
Children: Bernard Coyle 1892-1917, Ellen (Nellie) Coyle 1894-1965, Walter Coyle 1896-1986, Peter Coyle 1900-1952, Rose Coyle 1901-1902
Mother: Mary Jones 1843-?
The family lived at 69 Clifton St, St Annes, Lancs in 1911 (surname incorrectly recorded as Boyle in Ancestry census data).
In the 1891 census they lived at 6 Rifle St, Haslingden, Lancs but the 1911 census gives some of the children's birthplace as St Annes so I think they moved there about 1893.
I have been through all the (Ancestry) census documents for St Annes for 1901 and the odd numbers of Clifton St seem to be missing. The district 12 census lists the even numbers but none of the others mention Clifton St on their cover page (I haven't looked at every image except on district 12).
Ancestry doesn't come up with any matching search 1901 census information for this family whereas findmypast comes up with a Maria Coyle in the Fylde district (which would include St Annes). I can only view Ancestry data so would be grateful if anyone who has a subscription to other sites can check for this family.
Many thanks.
