I am looking for two brothers (Ernst and Friedrich) and two sisters (Ernstina and Berta) of my Great-grandfather, Reinhold Gutzmann. He was born in 1862 and died in 1913. He was born in (Schwetz) Swiecie, West-Prussia, where we presume his siblings were also born. We believe Ernst had a daughter by the name of Clara. If anyone has any information about these siblings, please let me know either by posting here or e-mailing me directly. Thanks.
