I have more info.Look at the family tree you have and you should find Conrad Mader, born 1769. Conrad had 2 sons, Andreas (born 1803) and Johann (born 1814).
Andreas is my husband's great-great grandfather.Johann is your great-great-great grandfather.
Your great-grandfather, Louis (married to Emma Lorenzen) was born and married in the USA. His father, Adolph was born in Germany and married in the US.
Contact me directly for more info.I also have the e-mail address of a man who is married to Ralph Mader's niece.He's been doing research and his wife is more directly related to you. I'll give you that info., too when you contact me.
