Hans is identified as having come from the German Palatinate and is known to have been a Mennonite.  It is possible that he is the Hans Meier who, in 1693, signed a letter as the leader from Rudelsheim for Mennonites going to Friedrichstadt. 
His date of arrival in Pennsylvania has not been confirmed, although some sources identify his arrival as early as 1709.  He is believed to have travelled with his wife, Ana (formerly Brubacher), and at least six children ( Hans Conrad, Jacob, John / Hans, Onela / Annalee, Elizabeth and Mary), but it is possible that members of the family travelled separately and some arrived earlier than others. 
The first confirmed documentation for Hans is his purchase from Hans Groff of 400 acres of land in Groffdale, Earl Township, on 30 Dec 1718/9. In February 1719 he purchased from John Farrer a second tract of 150 acres in Strasburg in the Pequea settlement, fronting onto the Conestoga River and adjoining the 350 acre tract purchased earlier in 1717 by his son, Hans Conrad. 
Hans lived here until his death early in 1722. His will was dictated on 30 Jan on his deathbed and names his wife as Ana Brubacher, to whom he leaves his plantation of 150 acres along with all buildings and belongings. Jacob and Johannes Moyer were named as Executors, and the will was signed by Johannes and Jacob Meier (assumed to be his sons), and Hans Burkholder and Christian Herr (both bishops of the Mennonite Church). 
Earlier notes referenced the birth of a son, Hanns Jerg Mayer on 27 Jun 1692, son of Hanss Jacob and Anna Maria, (citing Germany, Select Births and Baptisms, 1558-1898 via Ancestry / Germany, Births and Baptisms, 1558-1898 via FamilySearch FHL Film Number: 1056904) but it is not clear that there is enough evidence to identify this as the same family.
More evidence is needed to confirm the existence of the children Abraham (b.1690), Gertrude (b.1691) and Graff (b.1693). All appear to have been introduced via unsourced gedcom uploads. Graff's purported birthdate is just 2 months before Jacob's purported birthdate, and it is highly likely that either Graff was not a child of Hans and Ana, or else at least one of the reported birthdates is incorrect.
More evidence - DNA or documentary - is needed to confirm Hans as the son of Johannes Meyer and Annali Bauman, and the date and place of his birth and marriage. Best identifies him as their son, with an estimated birthdate of c.1665, but apparently only on the basis of a network of family connections. It's not clear where the birth details in the profile have come from.
