Which clans in Singapore are affiliated to which primary schools?

If I remember right, only the Hokkien Huay Kuan clan has school affliations. I am not familiar with any other clan affliations. Mostly, it's sister-brother school affliations (MGS-ACS etc)

Singapore Hokkien Huay Kuan clan is associated to tao nan, ai tong, Nan Chiau Primary, Kong Hwa School and Chongfu School.
