Maddock is pronounced just like it's written: mad-DOCK (dock like "doctor").
Keelan, I would think, is KEE-lin, because
Caoilfhionn's pronounced that way (Irish spellings are quite different from English spellings).
And
Alina could be a-LEE-na, a-LIN-a, or a-LYE-na. Personally, I much prefer the first pronunciation. Especially if you're going to use
Alina as a short form of
Adelina or something like that.
If you have any more questions on any other names, we'd greatly appreciate it if you first searched for the name in question in the search box on the main page of Behind the Name. If you can't find the name you're looking for (or a name that's similar) already in the database, then you'd be welcome to ask us for info on this board (the General board). Thanks.
