Hello Nina
I dont know if you have heard of the The historical directories.Which are on line,Unfortunatly Cheshire itself is very sparse.I did look in the couple available no Granelli surnames at all in the 1914 directory.That is not to say there wasnt any,if they were boarding with someone,family,friends.They wont be on the Surename index,i looked under occupations and other things,but nothing.However the Directory for 1902 gives
Granelli.Angelo. Confectioner 33 Church Street Macclesfield
The only one in the whole book so might be yours.Our library has the directories for Cheshire not the full set unfortunatly,but if you would like me to see if i can find any Grannelli's let me know.
