More on the name Emily, and its saintly bearers.
Aemilia (yes there were some), two virgins, both martyred at Lyon (Lugdunum) anno 177. Their joint feast day, 2nd June.

Émilie de Rodat, born 1778 at Druelle near Rodez France. This lady founded an order called the Sisters of the Holy Family, apparently an offshoot of the Ursuline nuns. She died 1852, and was buried at the convent she founded. Feast day, 19th September.

Émilie de Vialar, born Gaillac, near Albi in the Pyrenean Midi, 1797. Founded, 1832, the Order of the Sisters of Saint Joseph of the Apparition (?). Died at Marseille, 1856; canonised 1951. Her feast day, 24th August.

The above was taken from this site.

Emilia Bicheria, reliever of headaches and gout, appears to be this lady, Emilia Bicchieri. Born Vercelli, in the Piemonte region, circa 1238. The obit, 1314, is the same for both Emilias. However this Emilia is only a 'beata', Blessed Emilia, not Saint Emilia, which wouldn't preclude her from effecting those cures; continue your devotions, cephalalgics and hyperuraemics.
This is another nun, and founder of a convent - "Beata Aemilia de Bicheriis de Poenitentia Sancti Dominici, fundatrix monasterii Sanctae Margarethae de Vercellis extra muros." She was beatified in 1769. Who knows? Maybe she's been canonised recently.
