Thomas Tubman of Peel, a merchant of the Island in the seventeenth century.

He appears in the Chancery records as a litigant over the covenants of the sea trade, suing Edward and James Taylor of Millom in Cumberland. The entry stands in the Chancery book for 1600 alongside a suit of Deemster Ewan Christian's, and modern work on Manx maritime trade cites the two together as instances of the kind.

The name is common in the Island's records of the period and it takes several forms. Thomas Tubman senior and Thomas Tubman junior both drew a soldier's pay of twenty shillings a year in the garrison accounts, along with a Sir William Tubman among the chaplains. A Thomas Tubman of the Bowling Green served as a sideman in the churchwardens' presentments. A Thomas Tubman signed among the Twenty-Four Keys at a Tynwald Court in the reign of Lord Derby, and a John Tubman signed the ecclesiastical constitutions offered to the Governor, officers and Keys in February 1703. A licence for the marriage of Thomas Tubman and Bessy Norris was among those granted by Thomas Parr on the south side of the Island, entered in 1693.

The spelling moved with the century. One antiquary tracked it through Tunman, Tumman and Tubman to Taubman, so this is the family that later held the Nunnery and gave the House of Keys two of its Speakers.
