Incestuous Marriages and Offspring in the Ptolemaic Dynasty

Towards the end of November last year, I wrote a couple of posts on Ptolemy I Soter’s family (you can read them here and here). In writing them, I made two discoveries. Firstly, that contrary to what I had believed, not every Ptolemy took his sister for his wife. Secondly, that it took a hundred years after Ptolemy I’s arrival in Egypt as satrap following Alexander’s death for the first child born of an incestuous union to be born.
.
As a result of these discoveries, I thought I would compile a list of who the Ptolemaic kings married and which ones fathered children with their sisters (or, as in one or two cases, another close relative).
.
The first draft of this post was written using Wikipedia. To make sure it was as accurate as possible, I checked Wikipedia against The Ptolemies of Egypt by Lieut.-Colonel P. G. Elwood (Arrowsmith, 1938). Where they were in disagreement, I went with Elgood. Information derived from other sources is credited where applicable. I am aware that Elwood’s book is now 76 years old so the information therein may have been superseded. If you know of any modern treatments of the Ptolemaic dynasty, do let me know.
