Hello again Tom,
You have confused me (not hard)

. My reply to you refers to your first post regarding the children of Andrew Baxter and Elizabeth Stewart. If this is correct you have the wrong birth date for William and some missing children.
In your second post you are now referring to Andrew's parents and I do not understand who you are talking about with "the death of a child and the subsequent naming of a later born child" and then you refer back to Andrew Baxter and Elizabeth Stewart's children.
If you are going to check on Andrew Baxter and Elizabeth Stewart's children in Edinburgh, please let me know which ones as I have most birth certificates, marriage certificates and some death certificates and I would be happy to confirm dates for you.
My apologies but you have confused me somewhat
