Please Help Identify Pottery Marks

I bought this vase because it is quite lovely. I have no idea who made it, though I have researched the marks. It is stoneware with a somewhat Asian design, and with one of the marks being a circled cross. I'm not sure if this is some tribute to Satsuma / Shimazu. I would dearly appreciate any information on this. I'm guessing it's American made. I have no idea what the signature is. One of the impressed marks is a circled cross. The other is 6 dots within a circle. Thank you!
