I think so?!

From Manxnotebook:
MYLREA, contracted from Mac Gilrea, a corrupted form of Mac Giolla Righ, Giolla Righ's son'-Giolla Righ meaning King's servant.
MAC GILREA [1511], ILLEREA [1598], ILLIREA [1599], MACLEREA [1601], MACCILLREA [1603], ILLERAY [1618], MOLERIE§ [1631], MCYLLERIAH [1650], MEYLREA [1654], ILLYREAH [1660], MALLEREAY § [1684], MOLLEREIGH§ [1690], MALLEREIGH§ [1691], MALLERY§ [1693], MYLREEY [1754], MYLREA [1750], and many other forms.
§ These forms look as if they were derived from Maol -righ, 'the King's tonsured servant,' and the old pronounciation, MOLDERAY, points to the same conclusion. McYLREA is the commonest form during the 18th century.
Found chiefly in Jurby, Ballaugh, Braddan, Malew.
