Would you find this marriage weird?

So a colleague I don’t know that well announced her engagement today. I was chatting to her about it and asked how she met her fiancé. She sort of laughed and said ‘Well it’s a bit strange - he’s my stepsister’s half-brother!’

I was struggling to get my head around how it works at first, but basically her stepmother has a child from her first marriage whose father went on to have another child (the man she’s marrying) with someone else. There’s no direct family relationship between my colleague and her fiancé - they’re not even step-siblings - but it just seems such an odd dynamic! Would you find it weird?

My brother in law's brother married his step sister- their dad didn't marry the step mum until children were grown up so they only met as adults. Lots of teasing but it's not that weird really.

I know someone married to her cousin and it does complicate things!

Not too tricky if all the ex and step relatives are civil to each but could you imagine if there is animosity Shock

TonTonMacoute · 06/09/2018 20:39

They are not blood relatives, and in fact you can marry a step sibling.

My next door neighbours daughter is married to her husband's son. So technically they are step siblings, altbough they didnt meet till they were adults. All of them live in the same house and it took us a year to figure out who was whose kid - because the men seemed really alike, but so did the women... it clicked when they explained :) I think that is a little odd. But not much... op situation isn't weird at all. Got to meet your future partner somewhere ...

No. Just a funny anecdote imo.

Excited0803 · 06/09/2018 20:48

Must be a bit weird for the step sister; it would be a little strange if they spent time together as children but not otherwise.

Like other posters my friend's mum's sister married her dad's brother, I think that's not unusual, though it does make the idea of cousin marriage even more icky. We have one distant cousin whose grandparents were first cousins and their grandparents were also first cousins, so her bit of the family tree has pretty loops. She luckily doesn't have physical defects, but she isn't very bright.

puzzledlady · 06/09/2018 20:51

But they aren’t related by blood - I see no issue OP? Strange you feel the need to start a thread about it though..

TooMuchPenis · 06/09/2018 20:53

It's not "wrong weird" but it's kind of weird weird. As in a bit random and might be odd for the stepsister.

OlennasWimple · 06/09/2018 20:53

It makes the family tree diagram a little convoluted, with a few crisscrossing "branches", but unless they were brought up together as close family, it's not the weirdest relationship I've come across

Singlenotsingle · 06/09/2018 20:56

My dp is my stepbrother. My DM married his df (both dead now). Not in the least bit weird.

Jesus, I just thought it was an interesting story! Some people...

My mothers grandparents were two sisters who married two brothers.

Every generation since then spend a fair whack of any family reunion or family gathering, or family anything talking about how first cousins are also second cousins and going over how everyone is related or some such random nonsense.

I reckon it's weirder that my family still go on about it tbh.

delphguelph · 06/09/2018 21:06

Dh's dad and his brother married girls who were cousins.

FlintyBadman · 06/09/2018 21:11

No, I don't find it weird.

TheWinterofOurDiscountTentsMk2 · 06/09/2018 21:12

You struggled to understand how two completely unrelated people got married? Confused

LuckyDiamond · 06/09/2018 21:18

It turns the family tree into a family bush

Notasunnybunny · 06/09/2018 21:36

I think that weird is the wrong word, it is undoubtedly noteworthy.

KanielOutis · 06/09/2018 21:41

Its interesting how out of a billion or whatever people there are in the world, one would fall in love with a relative.

Almostfifty · 06/09/2018 21:43

I know identical twins who married identical twins.

I'm sure their children are more siblings than cousins.

YolandaTheYeti · 06/09/2018 21:47

No, I wouldn’t find that weird at all. It’s quite tenuous. Kind of like marrying your brother’s wife’s brother or something. If they were blood relatives or grew up together that would be different.

I couldn’t marry my cousin for example. I know cousins do marry in the uk still, but I would find that a bit too close a relative personally. My only male cousin is gay anyway, so not an issue!

HerpDeDerp · 06/09/2018 21:48

My step-uncle married my first cousin from my Mum's side, people meet in all kinds of ways and fall in love.

I had a friend whose parents found out they are 4th cousins at their wedding reception.

On the plus side the guest list should be easy for your friend.

TheWinterofOurDiscountTentsMk2 · 06/09/2018 21:49

They are not related.

NonaGrey · 06/09/2018 21:54

I don’t find it weird, no blood relation at alll and they weren’t brought up together

Like others on this thread I know two sisters who married two brothers.

HolgerLowCarbingLoser · 06/09/2018 21:56

No, I wouldn’t.

MrsSarahSiddons · 06/09/2018 22:04

Nope, nothing to see here, move along.
