Alfons,
I have several people in my files from Ahaus.
In particular, I am searching for information and descendants of Bernard Heinrich Boier born abt 1817 in Quantwick who married my 2nd great Grand Aunt, Anna Maria Antonetta Wilpolt in Ahaus on Feb. 7, 1865 (catholic Church Marriage records on FHC Film # 1049338) She was born 3/5/1834 in Legden.
The Ahaus church Records also have a baptism for their Children;
1. Johann Gerhard Boier born 12/10/1865 in Quantwick. ( to Ber. Hein Boier and Antonetta Wilpohld. Taufpatben Joh. Gerh. Wilpohld and Catharina Buckhorn? Also noted in the record is he married Wansin on 27.9.1903 in ? Wullen ? Ahaus 7/1903, died on 19.7.1944 ? (standestamp?) Wullen ? Ahaus # 18/1944)

2. Maria Christina Boier
(4/10/1867 in Quantwick to Ber. Hein. Boier and Antonetta Wilpolt. Taufpatben Joseph Enning and Christina Berning.)

3. Joseph Boier born 3/28/1869.
(3/28/1869 in Quantwick to Bern. Heinrich Boier and Antonetta Wilpholl, Witness (or Taufpatben) Joseph Boier and Clara Enning?)

The church records end at 1870 so I do not know if there were other children.
