What Nationality Is Last Name Suleman?

I do not know but know it is claimed by Muslims since Suleiman the Magnificent is a famous leader of the ottoman empire- he captured Acre from the  Christians- in fact some accounts have the Knights Templar escaping from him and carrying away the holy grail to Glastonbury-  Suleiman is known and revered to this day by Muslims.

Suleiman the Magnificent was the Sultan of Turkey (1520-1566) under whose governance the Ottoman Empire reached the height of its power. Also known as the Lawgiver, he built bridges, mosques, aqueducts, and fortresses, and vastly increased the expanse and wealth of the Ottoman Empire. Suleiman was responsible for a proliferation of art and literature that is greatly valued even today.

This is one spelling of suliman, suleiman, or sulaiman.  It is an Arabic name which might be adopted by any muslim peoples including muslim Filipinos, Indonesians, etc along with the original arabs.  The father of the octuplet woman is reportedly Palestinian.

Suleman is actually a Jewish name In Hebrew, Urdu, and Arabic we say Suleman meaning  (Soloman) in the old testament.  It is the same son of David mentioned therein. In English language the same name is known as Solomon or Soloman.
