Maximiliaen van der Leure

"The first of the family who settled in Ireland was Maximilian, a Dutch merchant, who obtained a fiant of naturalization, 1603" - Thomas Johnson Westropp, 'Notes on the Sheriffs of County Clare, 1570-1700' in 'Journal of the Royal Society of Antiquaries of Ireland', Vol. I, part 1, 5th Series (1890), pp. 68-80; available at https://clarelibrary.ie/eolas/coclare/genealogy/sheriffs/1665.htm

"Local folklore suggests that Maximilian Vandeleur was salvaging the cannon from the Spanish Armada ship Annunciada, scuttled in 1588 either on the Scattery Roads or on the beach at Scattery where she had been run aground so that repair crews could work on her, under licence from the Earl of Thomond in the first decade of the 17th century" - Senan Scanlan, 'Vandeleurs of Kilrush County Clare", https://www.clarelibrary.ie/eolas/coclare/genealogy/don_tran/fam_hi...

"Maximilian, a Dutchman, was the first of the name known in Clare. He occupied the mill at Sixmilebridge, and was a maltster and tanner there" - James Frost, 'History and Topography of County Clare' (Dublin, 1893) page 409; available at https://www.clarelibrary.ie/eolas/coclare/genealogy/don_tran/fam_hi.... Frost names him as father of Giles, but chronologically it seems more likely that he was the father of James, and this is reported in Clare County Archives, Vandeleur Exhibition, page 5, https://www.clarelibrary.ie/eolas/archives/Vandeleur_Catalogue.pdf

Notarial deeds in Rotterdam in 1621 record the administration of the estate of Maximiliaen van der Leure, deceased in Ireland at Cappeag or Cappeach in the county of Thomondt or Thoumont.
