Not much update in this, but a nice article from the NY Times:

With Shovels and Science, a Grim Story Is Told

It concludes:

A year ago this month, the remains of four Irishmen and one Irishwoman, 180 years dead, were buried beneath a limestone Celtic cross in a cemetery just outside Philadelphia. The search for their shantytown comrades continues; Mr. Bechtel has already found a "very concentrated anomaly," 30 feet deep, that the team hopes to excavate sometime this year.

Meanwhile, research by Dr. Patterson and Dr. Monge found that some Ruddys in County Donegal are known to have a certain dental variance: the absence of an upper right first molar. That fact, coupled with the passenger list from the John Stamp, prompted the decision by the research team to ship back to Ireland the remains of the first victim they had found.

Three weeks ago, the Watson brothers joined a small crowd gathered in a church cemetery in the small Donegal town of Ardara. They prayed and sang under a limestone sky, as a young laborer, late of Duffy's Cut, received his delayed but proper burial.
