William George Lambert was possibly the Mr Lambert who attended the first Powerscourt conference .. see the contents page.

William George Lambert's "Call to the Converted" and John Synge's reply to it ("Observations on a 'Call to the converted'" were discussed in my essay on "John Synge and the Early Brethren". However that was published nearly 40 years ago! About 20 years later in 2000 I provided some details of Lambert's career at Oxford where he was associated with B W Newton and Charles Brenton with whom he seceded in 1831 (in "From Awakening to Secession" 256-58, 278-9) From his advocacy (at Powerscourt) of withdrawing from the Establishment, I'm pretty sure they are the same person.
