Is it possitble for the same person to be both my first and second cousin?

A and B are brother and sister.

C belongs to A and D belongs to B, are each of their own children. This makes them first cousins.

C and D's children have children, this makes them first cousins once removed or 2nd cousins.

The children of the children of C & D are first cousins, twice removed or 3rd cousins.

And so on...

I do hope that didn't confuse you more. As it can be a bit more involved with all that. As the farther away you get there are actually 2,3,4 and more cousins as you go along.

I am my own 3rd cousin, as my mother and father were 2nd cousins.

For someone to be both your 1st and 2nd cousin, they would have to be a child of your aunts or uncles as well as a child of one of their children. unless there was some other type of incest, that I can't fathom at this moment.

As all your mother and fathers nieces and nephews are your 1st cousins.

Let's say John and Mary are brother and sister.

They have Mike and Paula, who are first cousins.

Either Mike or Paula would have to have a child by one of their other cousins to produce such a child.

Unless this goes out of one family and into another, like brothers of one family marring sisters of another family.

Dahhh!

First cousins share a common pair of grandparents. In other words the children of either of your parent's siblings are your first cousins.

Second cousins share a common pair of great grandparents. In other words the children of either of your parent's first cousins are your second cousins.

A simple way for someone to be both your first cousin and your second cousin is for him(or her) to be a first cousin on the side of one of your parents and a second cousin on the side of the other.

Let's say your father's brother( or sister) married your mother's first cousin. Their child would have the same grandparents as you on your father's side -first cousins- and the same great grandparents on your mother's side- second cousins.

It is also possible that someone be both a first and a second cousin on the same parent's side of the family. This means that at some point cousins married.

I have been studying my own genealogy for a few years and all the above examples have happened in my family.

Yes; however, your parents would have had to have had some degree of relationship prior to marriage. In order for a person to be your first cousin, you would have had to have had a common set of grandparents. In order for them to be your second cousin, you would have had to have your common ancestors be a set of great grandparents.

Lets look at an example:

Tom Jones

Father: Jim Jones Mother: Jenny Smith

Fathers parents John Jones and Sallie Johnson

Mothers parents Daniel Smith and Mary Jones

Mothers grandparent John Hones and Sallie Johnson

Lets say that Tom Jones is your cousin and your common paternal grandparents are John Jones and Sallie Johnson, making you first cousins. Toms maternal grandparent would have had to have been a child of your paternal grandparents (or a relationship similar to that) to have the same person be a first and second cousin. I hope this helps,

Yes it is possible for the same person to be a first and second cousin. Cousins is a parallel relationship on the family tree. I find diagrams help me best:

A = parent to "B", grandparent to "C", great

grandparent to "D"

/ \

B B = brothers and/or sisters to each other, aunt/uncle

to "C" of the opposite column, parent to "C"

in the same column

I I

C C = First cousin to each other, grandchildren to "A",

neice/nephew to "B" of the opposite column,

child to "B" in the same column.

I I

D D = 2nd cousin to each other, 1st cousin 1x

removed to "C" from the opposite column,

child to "C" in the same column, great-

grandchildren to "A", grandchildren to "B" in

the same column, great neice/nephew to "B" in

the opposite column

In other words, for example, you have your mom and she has a brother. He would be your uncle. His kids would be your first cousin. You both share the same grandparent. Ok, your first cousin's kids would be YOUR first cousin 1x removed, but they would be 2nd cousin to your kids. Then your 1st cousin 1x removed has kids. They would be grandchildren to your 1st cousin, they would be your 1st cousin 2x removed; they would be 2nd cousin 1x removed to your kids, and would be 3rd cousin to your kids' kids.

Clear as mud, I'm sure. I tried. This concept is difficult to explain very clearly.

I think second cousin is that your cousin has a kid and you have a kid. Those kids are second cousins. Or you're the second cousin to the kid. I'm a little mixed up there.

yes, your first cousin is your parent's sibling's child; your second cousin is you parent's- sibling's- child's- offspring.Thus if your parent's sibling'schild's offspring was adopted by your parent's sibling that would make that person both your first and second cousin.

my daughter and my nephew are first cousins, their children are second cousins. next generation, my sisters grandchildren are cousins

Have a look at this relationship chart, I'm sure it will help.http://genealogy.about.com/library/nrelationshipch...

In Arkansas, it's even likely! ;-)

Sure, if your paternal grandfather's second marriage was to your mother's sister, for instance.

of course. especially if you go to a family reunion to meet girls!
