GoCo Technology Demand Generation Manager interview questions

The interview went well and was standard. The individual from Talent Acquisition explained more about the company, the benefits, the team, and the role. Though they also asked if I was married and had kids. Both of which (as far as I know) go against what companies are allowed to ask in an interview. It has been a couple of weeks, and I have heard no response, so I guess I should have lied and said I had kids?
