Once again trying to find a connection on the De Leon's from Jalisco and Nuevo Leon

I know there are De Leons in Jalisco,Nuevo Leon,Puebla, Mexico City and other places
I was lucky to find a Book on Ebay Called Matrimonios en la Ciudad de Mexico 1568-1577 Primer libro de Matrimonios de La Ciudad De Mexico where some De Leons are mentioned .I have compiled some lists on this the Leal and De Leon since this is the same family and also my Paternal Line ,My wife's line has De Leon also but her's are the ones from Jalisco I'f I'm not mistaking

anyone out there researching the De Leon Line ?

Thanks!
