The nature of Scottish records is such that it is very unusual to be able to trace back beyond the mid-1700's with any degree of certainty. The reason for this is that marriage and death records beyond this period do not name parents. Therefore you may come across a birth in the parish records which you think MAY be yours, but it will be very difficult if not impossible to prove.
There are of course exceptions, for example if a multi-generation gravestone is found, or a family bible exists, but as I've said these are very much the exception rather than the rule.
Unfortunately there are individuals on the forums who then try to fit square pegs into round holes, and these entries end up being taken as fact rather than conjecture.
I'm not saying this is what has happened in this instance, as I'm not related in any way. But I just wanted to point out the pitfalls, and to advise you to use only documented proof for your findings, or ask subscribers where they sourced the information they have posted on the websites.
