Well. yes.
1. Roger's grandfather's son is Roger's father ( Grandfather - Father - Roger)
2. Rogers daughter would have Roger's father as her grandfather ( Rogers father - Roger - Rogers daughter)
give it up this is boring
This is true.
Yes
They could not vote if their grandfather had not been allowed to vote.
Yes, your grandfather's granddaughter could be your sister, making her son your nephew.
Your grandfather is going to be the parent of your father or your mother. Most people have two grandfathers. In families where there has been divorce, there could be multiple individuals referred to as grandfather.
Your great grandmother's daughter's daughter (i.e. your great grandmother's granddaughter) is you mother, your aunt, or your first cousin once removed.
Yes.
yes it could because your grandfaher has genes that affect your avereage body
It could be your grandfather. Or it would be a great uncle.
I'm not sure who Roger is, but yes, the relationship is quite possible. Roger's grandfather's son could be Roger's father; His daughter's grandfather could also be his father, one and the same person. lol
You can't have a grandfather 5 times removed. You could have a 5Great grandfather. In which case the relationship would be your 3Great Grandfather.
They added requirements such as owning property and passing literacy tests. Former slaves owned no property and it was illegal to teach them how to read or write. Even if former slaves could read, the tests given to them would likely be rigged somehow, such as being given in the wrong language. The Grandfather clause was another, saying you could not vote unless your grandfather could. It was tied to the above two requirements. Since their grandfathers likely didn't own property nor were able to read, then they didn't qualify to vote either.
