I would like to add Bess's husband William St Loe to her profile.
I am not though sure of the correct name to use for him .
In her letters Bess signs as E Seyntlo and William as Wyllyam Seyntlo
She is addressed by her mother in law, Margaret 'St Loe' as My lady Sayntloo .
https://www.bessofhardwick.org/home.jsp (letters in 1560s)
In the national Archives there are records relating to the couple using Seyntlowe Sentelow and Sentlowe .
Future generations of the family living in Dorset at Fontmell Parva use the surname St Lo as in https://en.wikipedia.org/wiki/George_St_Lo Historians seem to use either St Loe or St Lo.
Whilst looking at what was already here I also found a number of unsourced duplicates for pre 1500 St Lo(s) They don't immediately show as duplicates because of the variety of names used. I think that this illustrates the potential problem.

I'm also not sure about protocol about just jumping in since this profile has several managers and don't want to barge in. She is also a notable though I'm not sure why she isn't an aristocrat!
