These two women have similarly styled dresses, which leads me to believe they may be sisters or another close relative.
Here we see a dress that looks to have been made of velvet or other napped fabric. The bodice is embellished with trims and buttons, many details to look at here. Her hair is dressed into an arrangement, then appears to be covered with a net and decorative headband. It reminds me of the Renaissance style of hair covering called a hood, but really only in a tangential way. A hood has a lot more going on with it than we see above.
The jawlines on these two ladies look very similar, plus with the nicely made clothing and also both wearing earrings, I am thinking more that these are sisters.
