Rev. Shulze, The German Church

You probably know this information from the Irish Times site http://www.irishtimes.com/ancestor/browse/records/state/anomalies.htm:
he Schulze Register:

The General Register Office also holds the 'General Index to Baptisms and Marriages purported to have been celebrated by the Rev. J.F.G. Schulze, 1806-1837'. Schulze was one of a group of eleven Dublin clergymen, known with Dublin bluntness as 'couple-beggars' or 'tack 'ems', who specialised in clandestine marriages between 1799 and 1844. The records of the other ten were destroyed in the Public Record Office in 1922, but a court challenge in the 1870s resulted in Schulze's marriages being declared legally sound, and two volumes of his records were acquired by the GRO. They record 55 baptisms and c.14,000 marriages. Most of the marriages, celebrated at the German Lutheran Church in Poolbeg Street, Dublin, are for the years 1825-37 and record only the names of the contracting parties. The original is held in GRO headquarters in Roscommon. The LDS copy is on film 101771.

Some further information on the Rev Schulze from the newspaper archives - some of the people he married had assumed names, so the register may not be all that useful:

1853 Rev Schultze's register was produced in the King v. King court case; this register had been lodged in the consistorial court where it had been given in evidence in the 1842 Rogers v.

Further on the Rev Schulze marriages - these have been included in the IGRS marriage database compiled by Rosalind McCutcheon. You can search the database at http://www.irishancestors.ie/search/marriage/index.php -

I managed to find a marriage for my gggrandfather in the German Lutheran Church which gave me the name of my gggrandmother after 3 years of searching. This has led to a breakthrough on her branch of the family tree.... happy days.
