Any breeder advertising white Labs is to be avoided - they only come in black, yellow and chocolate although some yellows are very pale cream but never white.
Lots of good breeders in the North West - your main things when choosing a breeder are that the parents must BOTH be hip scored - ask to SEE the documentation and eye tested.
Be prepared to wait - most good breeders will have a waiting list.
Its not normal for the breeder to own both parents - so don't assume they will - its often a red flag if the breeder DOES own both parents!
I assume you are aware that young Labs will delight in eating your house?
Our first stripped 3 rooms of wallpaer (only as far up as she could reach so the ceiling stayed pristine!), removed all the buttons from the cooker, ate a hole in the fridge, ate the tyres on our caravan, munched through all the flowers and trees in the garden and nibbled thru the phone wires twice .... pretty typical :)
My second Lab (crate trained) only managed to eat a hosepipe, multiple dog bowls, a hoover and countless shoes :)
They are also very "bitey" puppies - so your younger child would need briefing on how to manage that - they are also often very jumpy which isn't nice when the dog weighs more than you!!!
They are fabulous dogs but many people don't realise that en route to their fabulousness you do have monsters LOL
