i think i understand the inherent question but i need to say you've presented it in an extremely convoluted phrasing, by giving unnessacary information and repeating yourself.I've just remembered a idea I had for A Npc I was planning to use in A Edition 3.5 DAD Campaign but I never used the idea and I have a question about it. The question is would his mother being A Commoner that earned A Noble Title shortly after he turned 19 years, 2 months old make The Npc in the idea A Noble?
The Npc had A Common Born Mother gave birth 11 days after she turned 17
The Npc became A Adventurer when he was 19 years, 1 day old and his mother was 36 years, 1 week, 5 days old and just over, meaning within 4 days, 2 months after The Npc became A Adventurer his mother did something, I never decided what, that resulted in her being made A Very Minor Baroness
What I want to now is would being the son of A Women that despite being of common birth earned herself the title of Very Minor Baroness shortly after he turned 19 years, 2 month old make The Npc Future Very Minor Baron or would being the son of A Women that was born A Commoner that was only made A Very Minor Baroness shortly after her son turned 19 years, 2 months old mean that The Npc isn't A Noble
what you've asked here is 'would the adult son of a commoner woman who was raised to the rank of baroness shortly after the son left to be an adventurer also be granted the rank of noble'
i don't know the details of 3/3.5e and what rules there may be or not about noblehood, but unless you're using default lore this really sounds like something you need to Decide For Your Self based on the society you've created for your world, i could see the noblehood being passed down the bloodline due to him being her child but at the same time i could also see exceptions existing due to some factor of -it was explicitly only granted to the mother, -he was already born when she recieves the rank any potential children she might have would be nobles be he wouldn't, -being too old to qualify getting looped in by proxy or disqualified by already being self sufficient(adventurer).
i realise this isn't incredibly helpful for answering your issue.
