Alexander Fraser (ff=capital F) of the Royal Regiment of Artillery. Mr Sinclair of Petty, I think at the moment, though I'm suspicious of this, as I've never come across any Sinclair in Petty. It's very much a Caithness surname. Having said that, about fifty, all alive in 1810 in Petty, will undoubtedly immediately emerge. (There was a Sinclair at Fort George a little earlier, but a dead one, whose estate the Sheriff substitute Gilzean was engaged in sorting out, and Fort George isn't in Petty). Mrs Fraser, mother of the above Alexander Fraser two hundred pounds. If you take Alexander Mackintosh to have been alive in 1810, (and leaving two hundred pounds to a child you call Mr would be a bit eccentric, though Alexander Clark may well have been putting his will together in a hurry) then Miss Christain (sic) is left all in mid-air without anything - this is probably a lacuna in the copy, and unless another one turns up, the legacy will have to remain a mystery. But her title is clearly "Miss"- although the Clerk's capital M looks like a W, it's a double s at the end of the word. If the Alexander is Alexander Mackintosh himself, it would be logical to put his offspring before Ewen's, though Alexander Clark isn't all that logical later. So I think on balance she may well be Alexander Mackintosh's daughter.
..."these two last legacies to be applied to be applied at the discretion of my executors in the compleating the education of the said Ewen Clark McIntosh and..." "to Mr Rowland ??Warmour?? ??Backhouse?? twenty five pds (best guess, I'm afraid) John Grant wine merchant....Andrew??Dirkin?? of Southampton St Strand (perhaps there's a directory which will clear this up) To Mr Richard Cooper artist Mount Street Berkeley Square ( possibly at a guess someone who helped him with his brother James's executry, which involved a major sale at Christies and the delivery of a number of biggish paintings from Naples. James had wanted his banker and, he thought, his friend, Thomas Coutts of Coutts and Co to do it, but Coutts declined. Which reminds me, Alexander opened an account at Coutts' to do the executry. It might just be worth checking whther Alexander Mackintosh had one with Coutts, who had roots in North East Scotland and links to the Clan Chattan. If he did, and you are a descendant and can convince them you are, their archivist would give you access to it)... child of my friend Ewen Mackintosh now unchristened....the said Ewen Mackintosh... Mr William Ogilvie of Pimlico 15 guineas....Alexander McKenzie of George Street Adelphi and to his daughters (abbreviated "daurs" with a line over the top) Annie and Mary Mackenzie one hundred pounds each...Peggy Clark the servant of Mr Ewen McIntosh five pounds....after Sarah Bailey my best guess is "to Mr Charles Graves, Mr William Graves and Miss Nancy Graves twenty guineas each" - the middle name of Dr Anderson defeats me I'm afraid- Purcell? Purnell? Parnell? none of which seem very Scottish. But he was certainly a nephew of Robert Anderson the Inverness silversmith. And he was left nine hundred pounds.
I can't yet work out where Mr James Robertson came from - yes I can, Limehouse! James Saunders of Lambeth, i think. William Roper of Islington £50. To Mr Andrew Anderson (the silversmith's kin again, I think, of Tortola, To Mrs Hannah Anderson his wife fifteen pounds, and I think the next is Mr Charles Dean of the Temple.... Hope this helps.
