Senovia Landa

My great grandmother Leonor Miranda Landa was seperated from her parents Dario Miranda and Senovia Landa when she was about 5 years old.
A couple of days ago I found their Civil Marriage Certificate in Arteaga Michoacan

I found a Cenobia Landa from Michoacan living in Zacatecas in the 1930 census. Could this be my missing ancestor?
