Hello Elizabeth, I don't know much if anything about the laws in effect in Scotland in the 1600's and I don't know who Robert 1's parents were so that is pure speculation on my part in the hope that maybe someone had more information and was willing to post it on here. I just want to take this opportunity to thank you for all the time and effort and wisdom you have put into the Abernathy genealogy over the years and I hope you will continue indefinitely. I have not been to Scotland and don't know much about it except what I can find on the internet, maybe a native of Scotland will start posting on here. I hope. I don't know if you have looked lately but there are lots of Abernethys from Scotland - some Andrews and Arthurs and Roberts on the IGI. I have been taking kind of a break but it never lasts long. Somebody is Robert 1's father and mother. Who do you think might be eliminated?
