I have just seen your message regarding Elizabeth Meil.
There was only one find for Elizabeth in Orkneys for the time period, and I have given the details to you.
Are you using
www.scotlandspeople.gov. uk ? It costs £7 for 30 credits and you can view the index for 1 credit and 5 to see the actual parish record.
The death cert. info. is only as good as the person giving the info at death. I even got my father's place of birth wrong !!!
Only you can decide whether something is right or not. I have found some Peter Brown baptisms but will await your instructions. For Peter , I started at 1800 and found 3 in Orkneys
