For my fellow genealogists:
Maria de Islas y Sotomayor indicated in her will dated 8 Feb1713 that she and her late husband Agustin Lopez de la Cerda had five children(Felix Juan el mayor, Juan el menor, Agustina, Esteban and Antonio) and thatthey all married.  Her testament can beaccessed online in the Aguascalientes archives.

 
Felix Juan el mayor age 29 married 6 Feb 1701 AGS to ElviraLopez Muñoz (aka Elvira de Cobos), hijalegitima de Miguel de Cobos and Teresa Lopes Muños.  I stress hijalegitima because Elvira’s mother was deceased and her father was a priestwhen Elvira married.  On that same day inAGS Juan el menor age 27 married Teresa Lopez Muñoz (aka Teresa de Cobos),sister of Elvira.  When the brothersprovided their marriage information on January 17 and 18, 1701, one of theirwitnesses was Francisco Martin de Sotomayor, their primo hermano.
 
It appears that 1701 was a busy year for the Lopez de laCerda family.  On 20 Dec 1701 the two youngerbrothers also gave information to marry. Esteban age 22 planned to marry Josepha Ramirez de Hermosillo.  Antonio age 21 wanted to marry her sisterRosa Maria Ramirez de Hermosillo.  Bothwomen were born and raised in Jalostotitlan and were the daughters of NicolasRamirez de Hermosillo (deceased) and Francisca Gutierrez de Barba.  I assume they did marry although I do nothave the actual marriage dates.
 
Much of this data, including their ages, is available in the1699-1719 Marriage Information records of Cienega de Mata, Jalisco (Film640168).  You can find them on FamilySearch.  I'm reading off of an old Family Group Sheet and do not have internet links to give you.
 
So we have the two older brothers marrying sisters, as wellas the two younger brothers marrying sisters. As for the 5 Feb 1713 marriage of Juan to Anna Maria Muñoz de la Barba,I haven’t seen the document and assume it is his second marriage.  And I wonder who that Antonio could be whomarried Josepha Alonso de los Hinojos in 1695.  These are not my direct ancestors, so I don’t have extensive data.  For that reason I do not have anything onAgustina.
