You may see the parenthetical notation of sub con next to your ancestor’s name. This notation stands for sub conditione meaning under the condition or, put simply, conditional. This means that the original baptism of the individual was in doubt – whether because the original sacrament was performed in a different Christian denomination where the validity is in question or was an emergency baptism. Additionally, it may refer to a child born of a mixed marriage, where only one parent is Catholic. In such a case, there may be questions as to whether a baptism was performed at all and, if it was, if it was done at the non-Catholic spouse’s church.
