I Am Researching My Family Name Which is Tiddy I Have

I am researching my family name which is Tiddy.

I have discovered that most of my male ancestors
lived as miners in Cornwall.During the nineteenth
century many Cornish people moved to Lancashire in search of work.
My great-grandparents were Cornish and married in Lancashire.
My grandparents and parents were born there and lived the whole of their lives there.
