Margrave is the title given to noble who territories border to another country. The rank can be varies.
The FL is a bit tricky, because i don't know wether Duchess dowager is a thing because technically she's not the mother. And she's not the previous madam because she's not actually a madam before the previous duke died. The great madam is more likely.
The girl's title is a lost cause tho, because a lady didn't actually have a title. The one with the actual noble rank is the father.
But, what can we expect from MTL translation. The proofreader didn't even have a will to made it make sense.
I'm loving the fl so far but character's titles changing every so often even in the same chapter is seriously annoying, is the girl she helped a count's, baron's or viscount's daughter? is the old man a margrave or a count? is the fl the "former duchess", "duchess dowager" or "great madam"? just pick one and stick to it, they aren't interchangeable and they mean things
