Brian,
Yes to the Jesus College question.
HHB's father George (sometimes + Hamilton Lowther) Brown was the brother of my 2xg grandfather Daniel Brown.
As far as I can tell the family traces back to Alexander Brown baptised Ardachuple in the ph of Kilmodan Argyll 31 March 1777 via Inverchaolain, Rothesay, Greenock and Dunbarton.
George's second family with Eliza Mary Smith was notable for the spread of births between London, Dunedin NZ, Melbourne AUS and Greenock SCT!
I was not aware of the 1908 marriage to Charlotte Annie Bucknall until today or the final fate of HHB and Emily.
I have some information on his church to church wanderings through Canada and USA (building on a letter that my grandmother received from brother Graham Hamilton B in about 1915) but this peters out in about 1922...until he appears in upstate NY in the 1930 census + Emily B. The response I received from at least one church in Canada could be interpretted to convey that HHB possibly had strong opinions that did not always sit well with his parishioners.
I have some photographs but not from George's line.
I am happy to share information but unsure how to contact you outside the chatroom.
Regards,
David.
