Daniel Johnson Reece was his full name, Johnson was his mothers maiden name.
Because the Registration district was in Warwickshire, I supply the only Elizabeth Sumpter I could find in the 1901 Census in Warwickshire 9 Wills Street, Aston Manor (Civil Parish)
Sumpter Elizabeth Head Widow 47 Boarding House Keeper Leamington, Warwick " Ann Sister u/m 45
It is strange that she states a widow and her sister is also a Sumpter. Perhaps it was better to be considered married when running a boarding house. You need to purchase the marriage certificate, which would give more details.
I have been unable to locate them on a previous census, however if you search on the above link there is births for Elizabeth 1859 and an Ann 1862 both Aston. Spendlove
