All of the records I am presently scouring are post-1800, even towards the mid to late 1800s.
I am very lucky that generations of my grandfathers, going back to 1818, appear on irishgenealogy, and all their offspring. However, is it not strange that almost NO marriages appear for any of their large numbers of siblings and families, so their records all begin and end with a baptism. All dead ends so far on my tree. Yet my second great grandfather appears as a sponsor on literally dozens of other marriages in the area, to names I cannot link into my tree.
In other branches of the tree, I have marriages in the mid to late 1800s, with parents documented, yet there are no baptism records, and the families were definitely in those parishes.
I would expect gaps here and there, but there are literally dozens of individuals in the St. Nicholas, St. Catherine and Harrington Street districts, whose baptisms should surely be there somewhere, in the 1800s, yet are not to be found, under any spelling variation. People who appear in the census in 1901, and people whose burials are recorded in Glasnevin. Who never moved out of that city area. But no baptism records. That is quite a large margin of error. Do other people find such glaring holes in their searches?
