[Wikidata] Filtering Human on the Given Name

[gilga gilga]

Hi to all!

I'm very new to Wikidata sparql, and I've only finished the tutorial.

My question is about filtering people on their given name.

I've tried:

SELECT DISTINCT ?person ?personLabel WHERE {
   ?person wdt:P31 wd:Q5.
   ?person wdt:P735 ?givenName.
   SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
   FILTER(STRSTARTS(?givenName, "A"))
}
LIMIT 1000

But there are no results (I'm filtering on the person with a given name 
starting with an "A").
What am I doing wrong?
Thanks a lot in advance!
Cheers
