January Capricorns

I have a lot of January Capricorns in my family. Granted, we are all born within the last 5 days (January 14-19), but nonetheless Capricorns right?

My partner (18th) and my grandma (19th) just don't feel like Capricorns. Maybe it's their Leo Moons? Edit: I'm Jan 14th, Libra rising & moon.

They're similar in how their booming voice takes up the room, and they dominate the conversation while putting people at ease with their presence. Witty as hell and a good time, but retreat to be alone to recharge after all the energy is spent.

Financially... not always in the best place and honestly got the short stick in life overall. It's not that they don't work hard, but they have seen a lot of struggle in their lives and not rewarded for the fruits of their labor.
