Hi Cynthia,
Julián Romo de Vivar's father Baltasar Romo de Vivar is my 9th Great Grandfather. I descend from Baltasar's second wife, Francisca de Lomelín. Julián Romo de Vivar is the child of Baltasar Romo de Vivar and his first wife, Catarina Muñoz de la Barba. The record you're looking for is in the same roll of film you're in, but, image 290.
Mexico, Aguascalientes, Catholic Church Records, 1620-1962, Aguascalientes, Asunción de María, Bautismos, 1701-1719, Image 290 of 511
