if I sent an email to the Polish Archives written in English, do you think it likely there would be someone there who could translate it to Polish? Is there usually a service fee?
You can write in English, but it might take quite some time to get a response, which is - at least in my experience - always in Polish. Provide as many details as possible, and if you're lucky you will receive a message telling you to transfer a certain amount of money to Poland for the copies they will send you. Fees have to be paid in advance and are very reasonable.
Is it common to have 3 villages, so close in proximity to each other, with the same name?
Oftentimes, there were remote farmhouses that (administratively) belonged to the same village.
