There is a John Yonce b. 1747 listed in the 1810 and 1820 Censuses for Rockland, Berks Co. that I assume is the same John Youse that you are referring to. His eldest son Jacob b. 1787 is also listed in the 1810 and 1820 Censuses for Rockland, Berks Co. as Jacob Yonce but in the 1830 Census for the same area he is listed as Jacob Yus. The second son of John Yonce b. 1747 also named John Yonce was born in 1789 and he is listed as John Yonce in the 1820 Census for Oley, Berks Co., as John Yus in the 1830 Census for Rockland, Berks Co., and as John Youse for the 1840 and 1850 Census listings for Rockland, Berks Co.
I am confused as to whether this family is a Yonce or a Youse. I have not been able to find any immigration data for a John Youse or a Johanne Jaus to help solve this problem. Help please.
