I may have misunderstood the original question, as I thought you wanted to get your relatives to come here to enter information, which is a great idea, although some of them may have to have an engraved invitation to get them here (if they're like some of mine
).
But if you are wanting a paper chart with blanks they can fill in, have you considered downloading a gedcom from here, importing it into your genealogy database software (you may need to add some tags to coordinate with Wiki-Tree's,) and then printing out charts for your relatives?
