Does JotForm offer any ancestry forms?

Do you have any ancestery forms/charts?

I'm not entirely sure what you meant so I'll just assume you're referring to something similar to these: https://www.ancestry.co.uk/download/charts

If that was the case, I'm afraid we don't have any templates that are specifically for these kinds of forms. You may need to build the form from scratch and design it upon your discretion. Seeing that you don't have any forms on your account yet, I will be listing some guides below that will help you get started.
