The Aljunied family were originally a fanily of traders and merchants who hailed from Hadhramaut.

[1][2] Due to Singapore's status as a free port, the Aljunieds found it profitable and migrated there.

[4][5] Syed Omar also donated land to be used as a Muslim burial ground, now known as the Jalan Kubor Cemetery.

[6] The Aljunieds resided in their mansion at High Street until they sold it in 1919, years after Syed Omar had died.

[10] The early Aljunieds, including Syed Omar, were buried at the Jalan Kubor Cemetery, until their graves were exhumed in the early 2000s to be reinterred in the grounds of the Masjid Omar Kampong Melaka.
