--------------------------
"Alice, da. of John de Lanhern by Margerie his wife, da. and heiress of Richard Fitz John. Living 30 Edw. I (1301-2). Styled Alice da la Hurne, Lady of Conorton, in a writ of quo warranto 12 Edw. I (1283-4), by which she claimed assize of bread, etc. in her manor of Connerton. Married to her second husband before 19 Edw. I. (1290-1).

Alice also married Sir John de UMFREVILLE of Penmark, son of Sir Gilbert I de UMFREVILLE of Prudhoe and Unnamed first wife or mistress, after 1280. (Sir John de UMFREVILLE of Penmark was born about 1234 in Castle Prudhoe, Northumberland, England and died in 1314 in Castle Penmark, Glamorganshire, Wales.)

In about 1240, Richard, son of John, marries his daughter Margery to John
Lanherne. John and Margery have a single daughter and heiress, Alice
Lanherne, who marries Renfrey Arundell between 1265 and 1268. Renfrey
Arundell dies in 1280 and Alice remarries to John Umfreville. Alice dies
between 1302 and 1311 but her second husband doesn't die until as late as
1322 and it is only then the Arundells gain possession of her vast
inheritance which included Connerton and Lanherne manors and the Hundred
of Penwith. By this stage Renfrey and Alice's son John is dead so it is
their grandson John II who inherits. This land stays in Arundell hands
until the seventeenth century.
