Born in Qld, one of nine children, to a pastoralist Walter John Biddulph (d.1905), and Harriette Sophia nee Foot (1839-1940).
The Biddulphs ran 'Mount Playfair Station', 1878-1903, and then 'Birtley Station' near Springsure.
Alice collected (numbered) MEL specimens (as 'Miss Biddulph') at 'Cungelella Station', 'Mount Playfair Station', Nogoa River, Springsure, Springsure Creek, and Tambo, 1890.
In 1904, Alice married a grazier, Edward Dunbar Wells (1877-1954), at 'Birtley Station'. The Wells moved to WA, where Alice's husband managed 'Oobagooma Station' on the Robinson River for three years.
On returning to the Springsure district in Qld, the Wells bred race horses. Alice's two daughters were both born in Qld. Alice died in Qld in 1971 in her 98th year.
