No wife has been identified.

The Borthwick clan website indicates he had at least three sons but only mentions William by name as his successor.[10]

Three sons (two of them priests) and three daughters are certain.

Note this WIlliam, 1st of Borthwick of that Ilk is different than his grandson William, 1st Lord Borthwick.

'Clan Borthwick' is unreliable as an authentic source. If only because the Borthwicks were never, ever, a clan. Their origins lie on the continent in Livonia, then Hungary.
