Was your Grandfather (b 1915) said to be an only child?
There are 2 more births in Lanchester district to TAYLOR children with a WILKINSON mother:
Olive in Jun Qtr 1918 and Margaret A in Jun Qtr 1919
Could great grandfather Thomas Edward have died after the war was over but due to the effects OF it, rather than having been killed during it?
