Rancho El Oceano Y Santa Teresa Jalisco

My research revolves around Ledesma,Cienega de Mata,Chinampas Jalisco. Recently I discover that my father was born in Santa Teresa, baptised in Ledesma Jalisco.I have looked for Santa Teresa around that area and cannot find it. Also One of his brothers was born in El Rancho El Oceano,cannot find that one either. These people were born in late 1800's and the places could now have new names. I would appreciate any info. Thanks Mary lou
