Cat Family needs rehomed (Murrells Inlet)

I’m not sure how to start this, we’re just over our heads right now.
My mother in law passed away, we had to take on some of her animals.
Unfortunately they had fleas and it’s gotten so bad our other animals now have them too.
We have a new baby and I just can’t do this anymore.
There’s one male, and two females.
The parents are about 3 years old and their daughter is about 2 years.
None of them are fixed.
We used to have a patio and the father and daughter used to love sitting outside.
We were second story so they couldn’t go anywhere.
We’re just in over our heads and they deserve a better life.
It kills us to have to rehome them, but know it will be better for all of us in the end.
The girls are white with tabby spots and the dad is fully tabby with a cropped tail.
He was a rescue and his tale was cropped when we found him.
