Coming from physically or originate from a place? (Ab Gallia venio)

Question

With "Ab Gallia venio. or "De Gallia venio". (Or other sentences of the same kind)

Could it mean both, I come from this place, or I am originated from this place (like a nationality, or the origin of my family)?

Answer 1

In Classical Latin:

• ā Galliā veniō means "I'm coming away/going away from Gaul" or "From Gaul I'm coming to.."
• dē Galliā veniō means "I'm arriving from Gaul" or "After/From Gaul I'm coming to.."
• you can also express this more naturally with dē/ā Gallīs veniō

The use of venīre in the sense you're after doesn't seem to be listed in OLD. Instead you can use:

• ortū sum Gallus
• ortus sum ā/ē Gallīs
• oriundus sum (ā/ē) Gallīs (acc. to Smith&Hall expressing a more remote origin, e.g. of the family's descent)
• in Galliā nātus sum
• ā/dē Gallīs, dē Galliā orīginem dūcō/trahō/habeō
