Hi can anyone please help decipher the Latin on the marriage of Matthew McDermott and Anne O'Hara at Cootehall on 9.2.1874. I can see that they are blood related - (san)guinitatis gradibus - but cannot read the rest of the entry. They are likely to be 1st or 2nd cousins as both had mothers with the surname Lavin.
Thank you.

  • Hi Fionn,

    To me it reads as

    in 4 in 4 consanguinitatis gradibus

    If that is what it is, it means they were cousins to the 4th degree, i.e. 3rd cousins.  They shared a common great-great-grandparent.

    All the best,

  • Thank you Mary.
    Degrees of consanguinity are confusing.
    Consanguinity seems to be based on degrees of separation i. e.
    1° parent, children
    2° grandparent, siblings, grandchildren
    3° great grandparents, aunts/uncles, nieces/nephews, great grandchildren
    4° great great grandparents, great aunts/uncles, 1st cousins, great grand nieces/nephews
    Based on that and the word "cousine" added to the marriage cert of Matthew and Anne, would you agree that they were 1st cousins?
    Best wishes.
