Set 3 Antique Blue White 19th Century Majolica Or Portuguese Plates Lemons

I can't figure out where these plates are from or what age honestly. They're not new but equally I don't think they're 18th century. I thought perhaps majolica 19th century. But then equally, what about Spain or Portugal.

with blue and white hand painted pattern. They've got three kiln marks on each plate underneath, the glaze is bubbly too.

One has a large crack visible in the photos, one has two cracks and one doesn't seem to. They have various minor chips on the rims. I'm tempted to keep them!
