There are an estimated 2700 graves

In the Burying Ground attached to Merion Friends Meeting. For 82 years, this was the only place in Lower Merion for burials. For most of its history, anyone might be buried there. I conservatively counted 263 Children on the burial record, but some have claimed 20% of the burials are of children.

Catherine Reese, a two year old who died soon after the Welsh settlers arrived in 1682, was the first burial in what would later become the cemetery. Thirteen years later, Edward Rees sold 1/2 acre to the Overseers for a burial ground. In the 346 years since, an estimated 2700 burials have been added, mostly Quakers, but also strangers, slaves, casualties from explosions at the powder mills on Mill Creek, and perhaps even Indians. Causes of all deaths are listed as follows: suicide, murder, cholera, yellow fever, tuberculosis, flu, softening of brain (it is unclear

what this referred to—perhaps dementia), consumption, fractured skull, lingering illness, run over by wagon, alcohol, erysipelas, nephritis, myocardial failure, drowning, powder mill blew up, bilious fever, heat prostration, carrying stones at paper mill, falling out of window, cardiovascular disease, covered by snow, cerebral hemorrhage, hives, typhus fever, smallpox, carcinoma of stomach, flux, white swelling (of joints), fall off trestle, stillbirth, fever, lockjaw, poisoning.

It sounds like the people who put together the burial record misinterpreted Joseph Price’s diary entry (based on the newspaper account of the burial of an Indian Chief in Philadelphia in 1792 (found by Nancy Webster): “According to the Daily Advertiser (Phila.), a prominent Oneida chief,

one of a delegation to Congress from the Haudensaunee (Iroquois), died age 28 and was buried with full military honors at the 2nd Presbyterian Church in Phila. All the city's clergy and a large crowd of citizens were reported as attending his internment on March 22. Named Ojikheta, he was a close friend and fellow soldier with Lafayette, who had him go to France and live with the Frenchman's family for over a decade. The chief's English name was Pierre Jaquette, in honor of the general. the March 27 edition of the Daily Advertiser had more, including the cause of death as pleurisy contracted on a long, wet and difficult journey to attend the government. 

This large delegation of about 50 indigenous leaders were specifically invited to Philadelphia by Colonel Pickering, Superintendent of U.S. Indian Affairs. They arrived March 13, "under the immediate care of Doctor Samuel Kirkland." It was the contact that began an official treaty process,

specifically the Treaty of Canandaigua, for which Quakers were the official witnesses for both sides.
