Am trying to figure out who the parents & siblings of the above mentioned Catherine (1742-1790) are. She married John Quane (1728-1815) Does anyone have this particular Catherine Tear/e on their tree?

This is her MI:

Braddan Burial Register
495

***Sacred to the memory of CATHERINE QUANE als TEAR of Ballavolley in the parish of Ballaugh wife of JOHN QUANE of Douglas who died May 15th 1790 aged 48? years***

Thnx, Carol
