@thegreenmeridianâ i come⌠with some more sources and possible non-answers because quite frankly it is history. (and iâm replying to op post bc⌠length mostly).
Iâll start with George McKinley Collins, or the possible ghost of. Basically, no proof exists of Georgey beyond his death. Him and Henry are 99% likely twins (as thereâs no reason like with the Tozer family to assume that they delayed baptisms), born somewhere in 1818 (likely) and then baptised.(1)Â
Thatâs the only confirmed mentioned of George. Anywhere. Itâs pretty easy to find the Collinses in the census, where they in 1841 happily show up with all their children, but not George. George also doesnât go to Greenwich Hospital School. I got to dig through the entire box that contained Henry Fosterâs admission, which had every person named Collins admitted (I assume 1728-1870 as on the Discovery description). Loads of Georges, loads of Henrys, no George McKinley. Henry was also a âthis is very close on being too old for itâ case, so if George went, he wouldâve likely been in the same box. By 1829: no George McKinley, not at Greenwich at least.(2)
What I did find, with the speculation of âwhat if he just⌠diedâ because sadly, thatâs what people just did, I went looking for Georges born around 1818 that died somewhere between that and 1829 and ended up with a George Collins who died in 1822 in Brighthelmston, Sussex, not all that far from Hastings. Iâve been unable to confirm if itâs him, because I only have a burial record and no one put a notice in the paper about this boyâs decease.(3)
Concluding, George McKinley did not go to Greenwich HS in 1829, nor did he live at home like Henry at 1841. Itâs kind of likely that he somehow died in childhood.
Secondly, Samuel Dowbiggin, who didnât really get mentioned in the OP post but alas, here he is, since there is a connection to the Collinses, though it doesnât necessarily explain why Henry would leave his estate to him.(4) Itâs indeed Major Samuel Dowbiggin, of Porchester Terrace, Bayswater (London, England).(5)Â
Ancestry has him in the 1861 census, which I happily looked at, first to confirm it was him, then to see if it was the mention you made of a census.(6) Also in that census is a Margaret F. Collins (29 y/o), Lady Servant, born in Ireland, aka Henryâs sister Maggie Foster.(7)Â
So basically, the connection so far is that Margaret likely went from living with her parents to living with Dowbiggin as a servant.(8) The odd problem is that at that point, Margaret is anywhere from 12 (1861 census) to 15 (1841 census) years old (please note that early censuses were known for being inaccurate), which makes Collins giving his estate to Dowbiggin just by that connection odd (as it may not have existed yet), but I guess there is just some earlier connection between the two families (or just Samuel and Henry) that isnât known â thereâs a lot of Henryâs past that we have no idea about.
Thanking @thomasblanky for rapidly answering my vague shouts about the Collinsâ family whilst I was searching since I donât know everything off the top of my head (and also for digging up some of these docs in the first place). Sources under the cut:
