What is your gender?
let's first look at the case where you are female:
my daughter's mother would then be... just you.
so then you are Theresa's daugher!
if you are male then
your daughter's mother is your wife (let's assume for now)
so Theresa's daughter is your wife,
and Theresa is your mother-in-law and you are her son-in-law.
