Hi f/e
Looking at the census returns they seem to have appeared in the 1880s - there is an entry for an Angelina Tognarelli, Ice cream maker, aged 43 in Sheffield in 1891 but I cannot see the name in 1881 or earlier.
RG12/3822/59/49
60 Little Pond St
Angelina Tognarelli, Ice cream maker, aged 43 in Sheffield
with Lea, her son aged 8, born Newcastle, her father Louis Lazzarina, 67, born Italy and niece Clementina Lazzerina, 9, born Lincoln.
(There is a place in Italy given in the place of birth - it looks like Instan? but that does not sound right. - might have to do a screen shot and post it for others to interpret)
More later this evening
Regards
Nell
