I got my father's height -- just average (though thickly thewed). My baby brother got his height from our mother's (five) brothers -- all of them are/were very tall, 6'2" to 6'7". My mother and most of her (six) sisters are in the 5'7" to 6' range.
There's some tall folk in my W's father's family too. My S's have always been in the 90-95 Percentile for height and look to be good sized when they're adults too.
