Clara Fischbach - Who is she?

The Germanna Foundation database has no daughter named Clara for Johan Fischbach and Liess.

They only list two sons who were both born in Trupbach.

The son Johan married Catharina Heimbach and the Clara born 1651 is their daughter so is it plausible she is named for her aunt,
Barbara Price, A509195?

-- do you have anything that is not in the database?

Thank you
