Why would siblings marry members of the same family?

[geneee]

I have four siblings in my family tree who each marry members of the same family. Two girls marry two brothers. Then the other two girls marry first cousins of those brothers. This is about 1800, lower middle class family.

Brothers in my family tree in the 1800s married sisters from another family.
Another relative married his wife's first cousin after his wife died. Also 1800s.

Limited options? If they lived somewhere lightly populated they wouldn’t meet that many suitable people.

"Two girls marry two brothers."

Maybe they just fancied each other? But, realistically, as KeirSpoutsTwaddle rightly says, in lightly populated areas there really may not have been much of a choice.

With subsequent marriages there may have then been pressure on the unwed women to get married following the first sister.

I also have more than one case where two brothers married two sisters and I even have a couple of examples of first cousin marriage.

Although, the first cousin marriage is rather further back than the 1800s

To retain the family’s possessions, usually land and inheritances.

It's basic. They had a small pool to choose from, so they chose what was available.

In my ex husband's family, his mum, my MIL, and her aunt married 2 brothers.
So the aunt and niece became Sisters in law. And one brother became Uncle by marriage to his younger brother, my FIL.

My 2 aunts married 2 brothers. One aunt met her dh and introduced his brother to her sister.

nothing wrong with that.

Ex’s DM and DF were in a similar situation - two cousins (both same aged only children, as close as sisters) married two brothers - this was in the late 70’s.

It was a little village in the north - apparently they just married who was close by, to ‘get on’

my DH married his cousin... what a mess that turned out to be! I didn't know this until well into our marriage but it explains a whole host of problems with DSC and his side of the family

So his uncle became his FIL. total nightmare

Limited options
dont have to split assets, especially something like a family farm can be worked together with less pressure on each woman to produce as many children.

The town where I lived in North West Kent is dominated by a handful of large families who have increased further still through intermarriage. So much so that many of the kids at one of the primary schools were all linked in some way.

There could be multiple reasons!
Limited people in their town/village
Religious reasons and only marrying 'within their religious community'
Only marrying within their social class
Family dowry where the women were 'married off' as younger girls to pay family debts to the other family
Keeping land/farms within the families

I'm not sure why you think it is strange.

I've known more than one sibling set go out with another sibling set.

My friends who were on a night out, who met two brothers on a night out. It's really not that odd, even in a large city in the 20th or 21st Century. One couple didn't last, but the other married.

When the population was smaller, and travel was MUCH more limited, it was clear it was even more likely that there was a smaller pool of potential husbands / wives to choose from.

There is a lot of this on my paternal tree either two siblings marrying two siblings or first cousin marriages.
I dont think it was unusual then.

Is your DH and his ex-wife from a different culture? Just curious as it’s clearly not due to limited options compared to the 1800s etc.

I have two family members (sisters) who are married to two brothers. All in their fourties. The elder sister got together with the brother of the groom at her sisters wedding.

I think this is an excellent example of why first cousin marriage is definitely not a good thing in general.

Wow, this thread got active all of a sudden in the last 30 mins

My grandfather’s brother married my grandmother’s sister. This was in the 1920’s.

^ this

Sarah Beeny's brother is married to her husband's sister.

i know two brothers who married first cousins. The younger brother got off with the younger cousin at the wedding of their elder siblings. Parents found out when she fell pregnant and encouraged a marriage. It’s been a nightmare for both brothers ever since as their wives’ family seem to find out about everything,even minor details, in their lives.

I have 2 sisters. One is married to a guy with 2 single brothers.

My mum is desperate for my other sister to marry one of them. She doesn't see anything odd in it at all.

I think it is ick personally. From a modern perspective, if one of the relationships/marriages ends then it would cause all sorts of hassle for family gatherings.

My first husband's Mum's sister married his Dad's brother - that was about 1970

Bit awkward when one couple divorced as they were still at all the same family dos with their new spouses - but they managed!

Some of these issues are property related. If there aren't any male heirs than a woman might be married to a cousin to prevent the property going out of the family.

Common practice esp when people didn’t travel far.
