She was heiress of Lower Carden

Leche lineage:

A family which assumed their surname Cawarden or Cawarthyn, from their place of abode in the county of Chester, where they had settled before the reign of Henry III, terminated in the male line about the time of Henry IV with William Cawarden, who left 4 daus, his coheirs, viz:

• Isabella m to Thomas Fitton, of Cawarden
• Lucy m to John Leche
• Eleanor m to John Golborne
• Margery m to David de Cluttone

The husband of the 2nd coheir, John Leche, who was living in the reign of Hen IV and then in possession of Lower Carden, in right of his wife, is made, by some pedigrees, a younger brother of the family of Leche of Chatsworth co Derby, “but”, says Ormerod “ there is a material variation between the higher generations of the Chatsworth Leches, as given in these pedigrees, and in abstract of deeds, from which, if correct, it appears that the family was settled in Carden as early as 20 Edward III, when Eva, widow of Hugh de Warin, releases lands in Caruthin to John Leche and Lucy, his wife, her sister, which John is said to be father of Leche, surgeon to Edward III, who, by patent (50 Edward III) was grantee of Castle Warin and other lands and was father of Daniel, the father of John Leche, to whom Jane, wife of John Preston, delivers lands in Carden 2 Henry IV and who obtained the lower Carden estate in marriage with Lucy Cawarden” John Leche left by Lucy de Cawardena son and heir, John de Leche
