Can anybody help me with the names of the 3 sons of Cheung Lai Cheun?

I have a few, but I'v heard of only 3, perhaps its a dialect of language mistake....

I believe one died young...?

Cheung Ping Lam (or Chang Beng-Lum)
Cheung Beng Fat (or Chang Beng Fat)
Cheung Sui Man
Cheung Kwock Chi

Thanks in advance.
