Baltzer on Family Tree Circles

I have my 5th grandmother Lucinda Ernst b. 4 Apr. 1824
in Lunenburg Co., she married Thomas Richard Brown born 1825 married 31 Bec. 1848 at Mohome Bay

In the early records of Lunenburg there is Lucinda Soph born 01 Mar 1828 dau. of Peter & Cath Martin Ernst, but the family on the net only has a son name Nathan as a child

I need help

Thank you
