My husband insists on letting his elders name my children, but I don’t want to. If you want to start it yourself, how can you convince him?

It depends on the name. If it sounds good, you might as well use it. If you really want to start it yourself, you can sit down and discuss it with them. For example, I think this sounds bad, why not change it to this one and tell them the meaning. I think if what you say makes sense, they will I will definitely respect you.
