I thought that the patronus ws a sub concious decision. Harry when he 
produced his first patronus didn't know his father's one was a Stag. I 
think he was thinking about his parents when he produced it so that's 
why it was a stag.
Maybe Ernie and Seamus were thinking of thinks related to the two 
animals when they produced their first patronus.
If Hermonie's one wa based on Ron then the explanation fits as she had 
thoughts about him from near the beginning of the books
