Dear Dolores, I have found the baptismal record of your grandfather in the old church books of the parish of Boleszyn. It is the last record at the bottom of the page (no. 19). Felix Wieczorek was born on 20 February 1860 at 11 p.m. in Boleszyn to pub owner Quirinus Wieczorek and his wife Marianna née Madrowska. He was baptized on 1 March 1860.
Does anyone know this place where Felix got his certificate?
