Squarcino also called Scarsini Borri - Birth year, in coordination with his parents' birth dates

I have just noticed that with a birth date of 1222 for Squarcino, his father would have been 9 and his mother 7, if their respective birth dates are correct.
Other sources (notably Geneanet) cite 1235 as a more likely birth date, close to the birth date of his wife...
