I found additional census records for John Ewalt who married Sarah Dunkley in 1749 in a recent trip to the archives in Philadelphia PA.
From "Collections of the Genealogical Society of Pennsylvania, Chester County Tax List, 1747- "
John Evolt -- Vincent, 1747
Jno Evolt -- Coventry, 1750
John Ewalt -- E. Nantmeal, 1753
John Evalt -- E. Nantmeal, 1754
These three three townships were all adjacent to one another.From deeds identifying Sarah as married to John Ewalt (see other postings), Sarah appears to have been living with John & Anna Patrick, her sister, in E. Nantmeal in 1748, prior to her marriage.All of their children would have been born in PA, not Bavaria as previously supposed.
John Ewalt was living across the river in Amity in 1760:
1760:"Johannes Ewald, Amity Township, Barks County, on the Manatawney, advertises that his German servant boy ran away. Jorg Kauffman, 16 years old." (ref. Hocker, Genealogical data ... from German Newspapers published in Philadelphia and Germantown, 1743-1800)
This John Ewalt may have been the child who immigrated in 1733, son of Ludwick & Agnes:

List 32 A -- a list of Palantine Passengers Come on Board the Ship Pennsylvania Merchant, 1733.John Stedman, Commander, from Rotterdam in Holland [Qualified Sept. 18, 1733]
True list, Philadelphia, Sept. 18, 1733
At the courthouse, 9/18/1733, 67 Palatines who with their families, making in all 187 persons, were imported here in Briganteen Pennsylvania Merchant, of London, John Stedman, Mr. from Rotterdam, but last from Plymouth as by Clearance thence, were qualified as before"from the Minutes of the Provincial Council, Printed in Colonial Records, Vol III, p. 518.
Sarah was the daughter of Richard & Esther Dunkley.Her siblings were Oliver, John, Ann, Jean, Anna, Mary, Hester, Rebecca.Her grandfather, Oliver Dunkley, was a carpenter at Pennsbury and purchased a lot in Philadelphia in 1688.By 1716, her father Richard was living in the Coventry/Amity area and worked as a skinner.
Because the tax reference found in the archives begins with 1747, John may have appeared on earlier Chester County tax records.I was only there for a matter of hours as part of another trip so no telling what more can be found there.He and Sarah may have known each other for many years before their marriage.
