Can Anyone ID Please ? Geranium ?

Evening all.
My sister posted a photo on facebook of a plant she found in her garden. She asked if anyone knows what it is, so I said that I'd ask on here.

It looks like a geranium or cranesbill, but we are not sure which one.
It is no more than 10" in height and has deep blue/purple flowers. The photo she posted shows a deep blue flower, but she said it looks more purple when you look at the actual plant.
I thought it might be meadow cranesbill, but the leaves are different. Does anyone know ?
She lives in south east Scotland, 10 miles south of Edinburgh. The soil in that area generally tends to be clay, but is more of a clay loam in her garden. She didn't say whether it is in her front or back garden, so her front garden is west facing and the back garden is east facing.
I have asked her if she could split a little bit off the plant for me

Thanks in advance

 

It's definitely a Geranium of some sort but I don't know which one. Sorry.

 

Thank you

 

Thanks @ARMANDII
I love those shades of blue

The closest I've found through looking online is the meadow cranesbill, but the leaves are not quite the same.
I know exactly what you mean about colours appearing differently on different screens though. I tend to check the greens in the background on photos, but even that doesn't always show true.
There aren't even any camera details in this photo's properties, so I don't know whether she used her fuji finepix or her kodak bridge camera
I'll ask her but it won't be until tomorrow. She goes to bed early as her daughter has school in the morning.

 

Thanks @ARMANDII
I'm wondering if it is a hybrid because I can't find anything like it anywhere on the net.
It just appeared in my sister's garden, she found it while doing a bit of weeding.
I'll give her a call later on to ask if she has any other hardy geraniums other than the Geranium "Chocolate Candy" we both bought at Gardening Scotland a couple of years ago.
G. "Chocolate Candy" has chocolate/bronze foliage and tiny pink flowers. We saw it on display on one of the trade stands so went back at the end of the day to buy it .
