I have a vague memory that several versions of TMG ago there was a discussion about dotted/ dashed/ wiggly lines to indicate dodgy/ unproved/ dubious ancestors in trees and pedigrees. Did anything come of this?
The reason that I ask is that I have just refound one of these people in my data but there is no way to spot this bad link, nor to indicate to any casual viewer of the website, nor to a reader of a printed chart that I have no primary proof of a certain generation.
