GeneralHeir of her grandfather, definitely, but not quite sure how.
Notes for Margaret Seton Lady of Seton
Definitely the grand-daughter of Alexander Seton, governor of Berwick.
Scots Peerage opines that she was presumably the sister of Alexander de Seton who had married Margaret of Ruthven and dsp. She m., by some means, Alan de Wyntoun in or after 1347; once she became heiress the large estates would be passed on to her children and so they had or used the surname of Seton.. Accepting this, her father was Sir John who dvp in 1327, and his father was Alexander who died around Sept 1348. And so it was her grandfather who signed the Declaration of Arbroath and was the governor of Berwick.
Interestingly a modern typescript, pub 1939, opines that Margaret’s father was Alexander the son of Alexander the Defender of Berwick. Pass! The author of the typescript was Sir Bruce Gordon Seton, Bt and he entitled it “The House of Seton, A Study of Lost Causes”, published by Lindsay and Macleod in Edinburgh 1939.
I cannot recognise the SP discussion in McAndrew’s book.
