The early generations of the Wardlaw of Pitreavie family, and the numbering of the Baronets, are very confused, and many differences are shown among various sources. Generations and parentage changes between sources in some cases, and some in one source are omitted in another.
For example, Sir Archibald, born 23 Jan 1793, per Cokayne, or 25 Jan 1796, per Burke’s, is shown as 15th Bt. by Cokayne, as 14th Bt. in the 1868 Burke’s, and as 17th Bt. in Burke’s 1914 and subsequent editions.
Here are three variations of the genealogy:
