Hi. I'm wondering what "their former" mean in this context.
Is it their own father? Thank you.

The Stepfather weighed over nineteen stone, broad as a bear in his embroidered velveteen waistcoat. He was clumsy around them, loud-voice, as if he were bellowing about in his warehouses. They forbade him entry to their salon. This freshly painted room was furnished with the choicest pieces from their former, grander home, the dainty-legged chairs and tables.
