I am participating in Amy Johnson Crow’s 52 ancestors in 52 weeks.
I have always had difficulties researching one of my Grandfather’s line.
My Grandfather, Alex Schneider (1898-1990) was born in Elberfeld which
now belongs to Wuppertal. I have his birth certificate, however I am not sure
if ever was baptized. Alex’s Father, Ferdinand Schneider (1855-1935) was
born in Berlin and died in Elberfeld. Ferdinand left the evangelical church at
one point in his life. I don’t know when and why he left the church.
Ferdinand was baptized in the https://en.wikipedia.org/wiki/Sophienkirche_(Berlin)
and he got married in the evangelical church in Gadderbaum, Bielefeld in
1883.
Ferdinand’s Mother, Caroline Francisca Amalie Büttner (1816-), was
married in 1841 at the https://de.wikipedia.org/wiki/St._George%E2%80%99s_Church_(Berlin)
Her church marriage record shows her age and her Father, but not when and where she was born.

Caroline’s Father, Franz Xavier Büttner (1790-1836) was born in Steinwitz,
Germany, which is nowadays in Scinawica, Dolnoslaskie, Poland.
Franz’s Father, Anton Büttner was born in Wöfelsdorf which is
nowadays in Wilkanow, Dolnoslaskie, Poland.

It’s nice to able to visualize on a map where one of my oldest known ancestor
came from.
Genealogy is not just an an adventure, but also a big puzzle. I still have to
work on this line and sort out some of the dates.
