My 3 were all different, but it's an urban myth that early walkers are late talkers and vice versa. The age they walk and talk at also has absolutely no significance as a predictor of later development or ability if they're within the very wide normal range.
DD (dc1) - crawled properly at 8 months but had been commando crawling (squirming about on her tummy and rolling about) from only just 5 months.
Walked at 9 months
Talked in 2-3 word sentences at 13 months and was pretty "fluent" sounding, using fairly grammatically accurate sentences with a very large vocabulary in two languages (because we moved abroad) by 24 months.
She's 14 now and a bit above average at most things, she's got an undeniable talent with language but isn't a genius despite very precocious early language skills, and is fairly sporty but only in a sport as a hobby way, early walking was no indication of future sporting prowess.
Ds1 (dc2) crawled at 8 months,
walked at 12 months,
first linked noun + verb to make simple sentences at 18 months and was chatting in more fluent sentences by about 2.5
He's the most obviously sporty of my children now; the only one who wins every race at sports day, is picked first for every team, rival (hobby, just for fun) football teams have tried to persuade him/ me to relocate to their team etc.
DS2 (dc3) crawled at 7 months
Didn't walk til 14 months
Climbed everything from 10 months though - slides, trees, bookshelves, bunk beds, vertical surfaces without obvious footholds ... 

Language development similar to ds1 although his second language was ironically slower despite being born in our adopted country because his older siblings insisted on translating for him!
The range of normal is wide and easily googled.
