Marriage record help

[jml1991]

Any help in deciphering the attached marriage record for Cosimo Blandino would be much appreciated. It is record #573, from 1677, from the town of Pietraperzia, Sicily. It begins at the bottom left and continues onto the top right of the attached page. Firstly, is it actually a record of marriage, or is it a "promise" of marriage? Also, his father is Santo, mother is Angela (deceased?). The bride is Anna, and her father is Giacomo, but I cannot read anything more than that.
Thank you very much for anything anyone can add to that.

Any help in deciphering the attached marriage record for Cosimo Blandino would be much appreciated. It is record #573, from 1677 not sure about the year, from the town of Pietraperzia, Sicily. It begins at the bottom left and continues onto the top right of the attached page. Firstly, is it actually a record of marriage, or is it a "promise" of marriage marriage? Also, his father is Santo, mother is Angela (deceased?) correct. The bride is Anna I read La Iaquina, but I can't find any reference to such surname, and her father is deceased Giacomo, but I cannot read anything more than that I can't read the name of her mother, either, though it's written.
Thank you very much for anything anyone can add to that.

It is possible that the mother's surname is LaCagnina

I don't think it's a capital c after the "la," given that it doesn't match with the C of Cosimo. Still struggling with it and checking endless (seemingly) lists of names to find a likely match, so all names being considered. Thank you!
