Background of John H. McCooey's wife Catharine

I am looking for any leads on Catharine I Sesnon's Spanish ancestry. My maternal grandmother, (Mary Ennis McCooey, married to Everett McCooey) used to tell us that she was from Spain. Any info appreciated about when she came to America and what part of Spain she might have come from. I have a lovely photo of her with one of her children as an infant.

Thanks!

Hi Frances,
Rich Ambro here, my mom was Helen, daughter of John H. McCooey Jr.
Unfortunately I have no background on our great-grandmother, Catherine, but would love to hear whatever you learn. I also have a couple of photos I'll try to attach or post. I'd love to see your photo also.
Keep us posted,
Rich
