Recently Rabbi Shmuel Reich of the Chabad Jewish Enrichment Center of Clearwater FL provided a 'Hatafas Dam Bris' for a Jew whose mother converted to Christianity before he was born, and arranged for him to go study in Yeshivah in Seagate for 3 months.
Aryeh Yehudah was born after his mother converted, his father isn't Jewish. His mother would take him regularly to a church led by none other than a 'Pastor Nuessbaum' – go figure, and he always subconsciously rebelled against it. Through this rebelliousness against Christianity he got involved with anarchist, death metal, and neo-Nazi groups which eventually led him to prison. In prison he discovered that he is Jewish through another prisoner who told him 'if your mother was born Jewish than you are absolutely Jewish', and that’s what really got him interested in learning more about Judaism. Through Rabbi Mendy Katz of 'Aleph', and Rabbi Shmuel Spritzer of 'Reaching out', he received Jewish material while in prison, as well as Rabbi Yossi Eber of Chabad of West Pasco who helped him out upon his release.
Recently he came back home to Clearwater where Bhashgacha Pratis he met Rabbi Reich, who – as mentioned above - provided him with a 'Hatafas Dam Bris' whereupon he received his Hebrew name 'Aryeh Yehudah', and soon after he arranged for him to study for 3 months in yeshivah 'Tiferes Menachem' of Segate. Aryeh Yehudah wants to live his life as a good Jew. He also wants to visit Israel, and grow in Yidishkeit one day at a time!" (source)
