1. Yes they could all be related, especially if they lived close together. Though obviously the link might be generations before. 2. The tithe records simply recorded the person who was the owner/leaseholder of each piece of arable land. So someone with several pieces of land would be listed more than once. 3. The parish of Easky has nearly 40 townlands in it. 4. Most Irish farmers held fairly small farms anything from 5 to 25 acres being average, all in the one townland. (Too many people and not enough land being a factor in the decision to emigrate). So not that many had land in multiple townlands, (but a few did). And of course some farms straddled 2 townlands so a bit of land in each could constitute the same farm. 5. In general I would assume different townlands meant different people. Compare the tithe information with the Griffiths Valuation information. With someone who does have several bits of land, you will often find in Griffiths that they are listed with a house, offices and land on the bit that they live on, and just land, or offices and land, or bog, or mountain, where they just have land on its own (ie no house). The other thing that Griffiths does well is separate people with the same name in the same townland. So if there are 2 Patrick Murphy entries in the same townland, you can assume it’s the same person. But where they are different people, there will be a note to distinguish them called an "agnomen". Sometimes the agnomen is a parent's name, sometimes a physical location of the person's residence, sometimes haircolour, occupation etc.
