It is very fascinating that two of out three of Merlin’s children in Arthurian literature are named after two legendary people (one fictional and the other historical).
For instance, in Richard Hole’s The Northern Enchantment, Merlin’s daughter is called Inogen (as shown above).
Similarly, in Monmouth's Historia Regum Britanniae, Brutus' wife is called Inogen.
On the other hand, in Sir Walter Scott's The Bridal of Triermain, Merlin's son is called Vanoc (as shown below).
In the same manner, in the play "The Briton: A Tragedy" (written in 1725 by Ambrose Phillips), Vanoc makes an appearance as the husband of Cartismand after she divorced her first husband.
Further research reveals that Cartismand is Queen Cartimandua of the Brigantes. According to Tacitus' Historiae, Cartimandua "grew to despise her husband Venutius, and took as her consort his squire Vellocatus, whom she admitted to share the throne with her" (The Story of Cartimandua as Relayed by Tacitus, 2021). This would make Vellocatus the inspiration behind the name Vanoc that appears in both Scott's poem and Phillips' play.
In conclusion, it is quite curious that later Arthurian texts use early names that are very familiar (for those who have read earlier texts). Moreover, it is very amusing to think that Merlin is quite the history nerd, being that he named one of his daughters after Brutus' wife and his son after the second husband of Queen Cartimandua.
