There is a lake and town of Chapala, near Guadalajara, in the state of Jalisco, Mexico. Could that be where your Siordia family comes from? Chapala is a resort town, famous through the centuries.
There is also a town of Jalisco. Small, not near Guadalajara nor Chapala, so your family may not have been from there.
I do not find places names Helisco nor Chapalo.
Hope this helps. Ed Nissen
