Was your Libbie Acker's maiden name Acker or was that her married name. There was an Isaac Acker that owned property in Rush, Monroe Co, NY. I found that when I was looking for Alexander Acker. I do not have much information on Alexander. I am searching for more, He lived in Rush and Henrietta, Monroe County NY. I believe he was born in Monroe Co, NY in about 1817. I do not know when or where he died. He is my gr,gr,grandfather.
