#110: You Want to Know…I Want to Tell You

110.1  Dear Stolf: “If Abner is my X, then I am related to everyone that Abner is related to.” How does one correctly fill in the “X”?   …from Xerxes Heidlfritz, Barracuda Beach, FL

chart 388

110.2  Dear Zerk: Please consult Chart 388. You are a blood relation to everybody in this chart, and your specific kinship is noted for each. Those shown in the dark blue ovals are the X’s…everybody related to an X is related to you. This is not true for the others…and it brings up the very significant asymmetry between your direct ancestors and your direct descendants…the former are all X’s, the latter are not. For example, you are related to everyone your father is related to, but not to everyone your son is related to…namely…

chart 389

110.3  …his mother! And of course all her blood relatives. Bringing “new blood” into a family line is called “out-breeding” (the opposite of the i-word) and is shown in Chart 389. The solid red mothers who are your direct ancestors are of course your blood relatives, as are their blood relatives…exactly the same as the solid blue fathers. But the white circle mothers are the “new blood” and are not related to you…thus their offspring and their descendants are not in the X category. And needless to say, half-relations do not fall into the X category either, since they have by definition a side of their family not related to you…in that sense a half-sibling resembles a full 1st cousin. For ease of discussion we can call X relatives “co-relations”…not to be confused with correlations, altho I can see how that could happen.

chart 390

110.4  But wait, sez you! What if my co-relation does marry somebody he is related to…what then? Well, it can go either way. Let’s assume your uncle marries somebody he’s related to. On the left side of Chart 390, your uncle marries A. And A is related to you, since A is related to a co-relation of yours, your uncle. But we will also assume that A is also a co-relation of yours. This makes their son, your 1st cousin, also your co-relation…there is no side of his family to which you are not related…you are related to both sides. The trouble with this scenario is that, as seen in Chart 389, your co-relations are very close relations…either your direct ancestors or their siblings. So A would have to be…well, the gentlest way I can do it is to make her your uncle’s aunt, your grand aunt…right side of Chart 390. Not something we do much these days, but not unheard of down thru history, as we have seen.

chart 391

110.5  But even tho that 1st cousin is now your co-relation, that’s where it would end…if he marries outside your family, as is shown in Chart 390…his son, your 1st cousin once removed, is not your co-relation. On the other hand, suppose your uncle marries somebody related to you, but not your co-relation, as shown in Chart 391…in this case he marries his 1st cousin, your 1st cousin once removed. Now their son…your 1st cousin thru his father, and your 2nd cousin thru his mother…is not your co-relation, because as you can see, he has a maternal grandmother B not related to you. Pretty simple when you think about it…it’s just not something people who don’t read G4BB would think about, I daresay. But it leads very nicely into our next question…

110.6  Dear Stolf: If somebody related to me marries somebody related to them, how does that effect me exactly?  …from Me, Identity City, VT

110.7  Dear You: I dunno…are you the type of person who tends to take things to heart? Seriously tho…it’s reasonably straightforward…say Abner is related to you and he marries Zoë, who’s related to him. The question is, is Zoë related to you? If she is, then you will have a double relationship with the offspring and further descendants of Abner and Zoë…if not, then it doesn’t effect you at all. Mind you, if Abner is your co-relation, then Zoë is automatically related to you…that’s what co-relation means. If Abner is your relation, but not your co-relation, then Zoë may or may not be related to you.

chart 392

110.8  Let’s continue with the examples we’ve been using. In Chart 392, your uncle Abner marries his aunt Zoë, who is also your father’s aunt and your grand aunt. You are related to their son Buck in 2 ways…1st cousins thru your father and Abner (left)…and 1st cousins once removed thru your father and Zoë (right), since your father and Buck are 1st cousins. That’s how it effects you…a double relationship with the offspring…when Abner married your co-relation.

chart 393

110.9  In Chart 393, Abner marries his 1st cousin Zoë, who is also your father’s 1st cousin and your 1st cousin once removed…thus your relation, but not your co-relation. You are again 1st cousins with Buck thru your father and Abner (left)…but now you are also 2nd cousins with Buck thru your father and Zoë (right). So in either case, your uncle marrying a relative of his, and by definition a relative of yours too, resulted in 2 lines of ascent between you and Abner’s son Buck.

 chart 394

110.10  Instead of your uncle marrying his 1st cousin, suppose it’s your 1st cousin Abner marrying his 1st cousin Zoë. You are related to everyone your uncle is related to, but not so your 1st cousin. If Zoë is also related to you, she must be your 1st cousin too, so there will be 2 lines of ascent between you and their son Buck…in this case, you and Buck will be double 1st cousins once removed…and your son will be Buck’s double 2nd cousin. But if Zoë is Abner’s cousin only on the other side…thus not related to you…there will still be a double relationship, as seen in Chart 394…only now, it’s Buck and his sister Brenda who are double 2nd cousins to each other.

110.11  You might think this means there is some kind of double relationship between you and those siblings…but there isn’t…you are 1st cousin once removed to each…and your son is 2nd cousin to each…but in this case neither you nor your son are double anything to anybody. Honest…I wouldn’t kid you about something like this…so hope to see you back here next week, deal?
