Baptisms Fernyhalgh, Lancs, mysterious Latin

[barbara lee]

I am extracting the Slaters from this RC register, in the form of the Catholic Register Society's printed transcription. I can manage the usual Latin but there are some interesting additions to some entries.
Can anyone make any suggestions about this one?

Anno Dni 1772 die 2° mensis Septembris ego R. Banister Sac. Miss. ad capellam B.V.M in Fernyhalgh baptizavi infantem masculum pridie natum ex Joanne & Helena Slater catholicis conjugibus in Ribbleton: cui nomen Jacobus est impositum: Patrini Hugo et Elizabetha Edmonson Infantis consanguinei in 2° gradu.

I can see it is the baptism on 2nd September 1772 of James son of John and Helen Slater of Ribbleton, godparents Hugh and Elizabeth Edmonson. I think "pridie natum" is "born the day before" but what about that consaguinity?

Google translate suggests it means “a child of consanguinity in the second degree”.
Google adds “(ii) Second-degree relatives include an individual's grandparents, grandchildren, uncles, aunts, nephews, nieces, and half-siblings. (iii) Third-degree relatives include an individual's great-grandparents, great grandchildren, great uncles/aunts, and first cousins.”

So does that mean that the baby’s parents, John and Helen Slater, were closer than cousins, perhaps uncle and niece?

Barbara, just an idea. Perhaps it means the Godparents were blood relatives via an ancestor in common as a Grandparent.

Good thinking. More complex Latin sites suggest "infantis" is "of a child". So perhaps the godparents of the child were the consanguineous ones, the child's uncle and aunt.
[The punctuation is odd - no full stop or colon after Edmonson, but capital I on Infantis]

Therefore, it would be via an ancestor in common.

Thank you both. The chart (from the University of Alabama)suggests 2nd degree consanguinity is brother/sister or grandparent/grandchild. Something to work on, anyway, as other Slater relationships reveal themselves.
