You need to see a lawyer who can send your old employer a strongly written letter that
1. If you lose your job with your new employer, you will bring an action for defamation and interference with contract;
2. If they continue to call your home and to call your husband at work, you will seek a restraining order. You will also contact law enforcement. Repeatedly calling with intention to annoy is a misdemeanor.
After reading your back-and-forth with Mr. Eschen, I suggest you stop posting any more details here on Avvo. There is no confidentiality here and anyone can read what you write; certainly any company familiar with social media will know just how to do that.
I agree you need to retain an attorney to show your former employer you are serious. In addition to a potential harassment claim, you may also have claim for tortious interference with economic advantage, false light, or other torts. These are things to discuss with an attorney in private.
