Greetings,
Here's the information we found on the name "Madog mac Morgan."
A form of "Morgan" does exist in Scotland. It is unclear how the name was transmitted from P-Celtic; it may have been adopted from Strathclyde or indirectly through the Picts. In any case, the usual form of the name is "Morgunn."
In Gaelic, nouns change form based on where they're used in a sentence. The "genitive form" is used with the phrase "of X." The standard genitive form of "Morgunn" is "Morgainn" but the genitive forms "Morcunn" and "Morcunt" are also recorded. (1)
It's less clear whether "Madoc" was actually used as a name in Scotland. One of our sources notes a Maddoc, Earl of Angus, from the 12th century. (2) However, this "Maddoc" is recorded as "Madeth" and "Madith" in other Scots sources and as "Madod" in the Orkneyinga Saga. Manuscripts during this period used a "c" and "t" which were easily confused, and we think it is likely that "Madoc" is a scribal error for "Madot." However, there's no reason you couldn't use a form of "Madot" as your name.
Thus, we would suggest using a name like "Madot mac Morgainn," or a variant on this name. This would be a perfectly reasonable Scottish name for your period.
