Has anyone else heard this saying….

[IncognitoUsername]

… or did my family just make it up?

When I was a child, if the sky was darkening due to incoming rain, my DM would say ‘It’s a bit dark over Will’s mother’s’. I grew up thinking this was a saying everyone used but if I’m honest I can’t remember anyone outside of our family saying it!
My DH thinks I’m crazy - or at least my family is. Please tell me someone else has heard this?!

I've heard it as '...Bill's mother's house', if that's any help. Not an idiom I grew up with, so I can't help with the origins.

No

‘By Jack’s Mother’s’ in our family - South Yorks

Will and Bill are similar enough for me!

Yes, my Mum used it and I do as well.

Also, if anyone takes the long way round I always say we had to go all the way past Will's Mother 's.

Goodness knows where it comes from. Mum was an Essex girl.

It's dark over Bill's mother's is definitely a Staffordshire (and thereabouts) saying.

Interesting that there appears to be regional variations. I grew up in Suffolk

It’s a bit black over Bills mothers. East Midlands based

Yes that saying was and still is used in our family - northern roots.

"Bit black over Will's mum's" - I'm from Hertfordshire, that's where I got it from. I've lived in Cheshire for 20 years, and nobody has heard of it.

My grandma said "black over Bill's mother's". She was northern.

It's Bill's Mothers.

Yorkshire sayings are the best.

You're not as green as you're cabbage looking. 🥬
They followed a dustbin wagon and thought it was a wedding 💒

Yes, use that one too!

Yes, this.

That is a great saying.

DHs family from the North East say "a bit black over Bill's mothers"

Never heard it where I came from in Lincolnshire /Yorkshire borders

I thought Bills mother was William Shakespeare’s mother.

my saying was when you asked as a child where was X was with Molly behind the wallpaper

Certainly used around the Staffordshire/Derbyshire border area, both my mum and grandma used to use it. It was definitely "it's a bit black over Bills mothers".

My parents say ‘it’s a bit black over Bill’s mothers’ - Derbyshire based

I think it means the weather is coming in from the west ( as it tends to in England) where Bill/Will means Will Shakespeare and Stratford upon Avon is west of most places.

"Black over Bill's mother's" in the Black Country, meaning stormy weather incoming, generally from the east. Not sure which Bill we're referring to though!

Well, I'll go to the foot of our stairs was another one usually used when surprised about something.

Worcestershire based and my nan always used to say it’s a bit black over Bill’s mother’s

Black over Bill’s mother’s. South west here. Also knew the cabbage-looking one, and if I went out to play, I was to be back “once it turns dumpsie”.
