"Of the families named above, the Macliers (or Macleans), the Sinclairs, and the Spaldings were the most prominent. We shall not enter into the fabulous genealogy of the Macleans, with their forty-two descents from some Irish chieftain, who was part-owner of an ark at the time of Noah. Suffice it to say that one Hans (John) Maclier, son of Hector Maclean, fifth Baron [sic] of Dowart, came to Göteborg in 1620, settled in business, and succeeded so well that he became a town councillor (1640-1650)."

"Forty-third in lineal descent from Inghis tuir le Amhir, younger son of an Irish king, came Gilleon, who lived a hundred years before Christ. From him in unbroken genealogy is traced John Maclean (son of the Laird of Dowat), who came to Sweden in 1639 [sic], and, settling in Goteborg, greatly aided in the building of that town. ..."

Such was the situation between James and John Maclean in Sweden. In 1629 the two men became business partners and John married Anna Gubbert, the sister of James wife."

"Hans Maclier var såsom redan nämndt gift med Anna Gubbertz, köpmansdotter från Stockholm, och hade med henne många barn, af hvilka dock flera dogo i unga år. Efter hennes död 1653 gifte han sig med Lilian Hamilton och, sedan han åter 1658 blifvit änkling, med öfverste Gordons änka, Anna Thomson. Själf afled han den 7 juli 1666. Hans båda hustrurs, Anna Gubbertz' och Lilian Hamiltons, konterfej hafva blifvit till eftervärlden bevarade, men mig veterligen ej hans eget."

Johan Macleer had been raised to the Swedish nobility in 1649, and in the following year was created an English baronet by Charles I as a reward for his services in helping Montrose. His Swedish wife had a sister who was married to Jakob Makeleer, a silk mercer in Stockholm. The two brothers-in-law were obviously related and possibly brothers.
