Research Notes:  The Ballynakill CP Tithe Applotments were transcribed from the GV pages 97 to 111 by Phyllis Edwards.   All recorded names are as spelled in the record.  All entries should be checked if you are trying to find connections to your family.  This resource is an index, since there is more information for each entry in the source document.  The Townlands and/or areas used old times spellings, so may not look familiar.
ADDED NOTE:  There are four Galway civil parishes named Ballynakill
