Qing Ming at Yeo Clan Burial Ground (Images from the Past)

The consistent description from the series of photos below describes Qing Ming (清明, Ching Ming, Tomb-Cleaning Festival) at a Yeo clan burial ground in Singapore. This is from the Elliot Collection which accessible online from the Museum of Archaeology and Anthropology website. 

To me, its another powerfully captured photo. The old lady in black paying respects to her deceased husband simple tomb with her granddaughter accompanying her. The offerings were simple as well and in the second photo you can see the backdrop of the cemetery, void of tree but full of lallang or tall grass. The Yeo Clan Cemetery / Yeo Clan Burial Ground / Heap Guan San of doesn't exist anymore, affected by Singapore rapid development and was exhumed post 1973 to make way for housing development.

From what I can figure out from the handwriting from the photo behind:
Hokkien Yeo Cemetery, Near Gillman Barracks Singapore.

The rise and fall of Heap Guan San - Yeo Clan Burial Ground 

From what i can make out, the ground was situated at Upper Telok Blangah. By a deed made between Madam Tan Geok Hup (daughter of Tan Kim Seng) and Yeo Hong Tye dated 8 November 1882, it was declared that the burial ground donated by them should be called "Hiap Guan Sun"  (Heap Guan San / Heap Gwan Sun) and all Hokkiens bearing the surname or clan Yeo should be allowed to be buried therein free of costs. The deed also contained the usual trusts as to the maintenance of the grounds and the appointment of trustees. 

In 1973, a notice of exhumation was published by the Resettlement Department Housing & Development Board to exhume the graves in Heap Guan San (Yeo Clan) Burial Ground situated on State Land Lot 117-28, 117-19, 42-2 and 42-3 Mukim I at Telok Blangah Road. Exhumed remains are either sent for cremation at Mount Vernon Crematoria or for reinterment in Chua Chu Kang Government Cemetery at Chua Chua Kang Road, 16 miles. 

The Heap Guan San Burial Cemetery Registrar is available from National Archives of Singapore and from its website, it mentions that the covering date range form 1905- 1968. You will find out the estimated number of burials if you manage to get access to it.  

From this notice  also, i got insight that there was a plan for reinterment of exhumed remains in a 4 acre site at Telok Blangah Road (Lot 117-28pt or 117-19pt Mukim I (next to Par Paint Factory) but this plan was eventually canned by the Government's decision in closing down cemeteries within the city limits.  The location was likely nearby where the Yeo Building is. You can make out where the tombs are located within the Heap Guan Village from the aerial photographs (the white crater marks).
