Hi,
The following may be of interest, but still doesn't help with the source of nursur as a name.
A search on forename Nursur brings up the following births;
Nursur C Alexander 1915 Jul-Aug-Sep Durham, Tyne and Wear
Nursur Cuthbert T Jones 1895 Jan-Feb-Mar Durham, Tyne and Wear
Nursur J Wilson Apr May Jun 1918 Gateshead Durham
Charles Nursur Bell 18 abt 1895 All Saints Northumberland
Charlotte Nurser Bird 1883 Apr-May-Jun Derbyshire, Staffordshire,
Joseph Nurser Watson 1838 Oct-Nov-Dec Durham, Yorkshire - North
Nurser Ann Turner abt 1860 Pentrich, Derbyshire,
Charles Nusser Mold abt 1890 Neithrop, Oxfordshire, England
The following is something I noted down; "Idi Amin's former army chief of staff, Maj. Gen. Yusuf Gowon, and his bodyguard, Nursur Gille."
