In year 1815; Britain: Would a Viscount's daughter inherit the viscountcy or would the next male heir would?

Question

I am working on something. I need to understand how the ranking titles worked in Old Britain. If a Viscount had only a daughter in year 1815, would the daughter inherit the title and all lands, or would she not gain anything? Would rights would she inherit? Thanks. So far, what I've learned from my research is that the next male heir in line would become the successor & gain all. Were there even 'wills' written out in year 1815 in Britain?

Answer 1

If she had a male sibling then he'd get the lot unless the children were all daughters then the eldest girl would get the loot but not the title.

Answer 2

The lands and title would be held in trust, until she was legal or married. The title would most likely go to her male heir. In some cases her husband would inherit the title, but I believe that was unusual. Or in other cases the daughter would get a settlement, but the bulk of the estate and the title would go to any male heir in her fathers family, a cousin or nephew etc.
Yes wills were written at this time, the protocol for inheritance was usually included in the will.
