The name John McIntosh came from the IGI database being the father of the only Alexander listed in Moulin or Dunkeld for this time frame. I also cross checked the information in the census information.
In going through the IGI databases I also investigated the idea that Alexanders father may have had the name of one of the other male children but again this turned up no information.
The information I have on Alexander came from the marriage banns of his son Charles who married Mary Leslie at Dunkeld and the 1841 Census. Charles and Mary are further listed in the 1851 and 1861 listing their offspring.
My proposed family line is as thus...
John McIntosh b. 16 May 1708, Moulin Perth father Robert McIntosh, Mother Jannet Rotson b. abt ?, married ? and had issue Alexander
Alexander McIntosh who was born about 1742-4, at Dull Perthshire Scotland and married on 8 April 1763, in Logierait, Perth, Grizel ( Grissel ) McNab, who was born on 18 March 1744 in Logierait Perth Scotland, and had issue a son John b. 9 May 1764 Moulin Parish , chr. 11 May 1764 at Dunkeld Perth. Grizel's parents were Adam McNab and Catharin ( Catherine ) Robertson.
John McIntosh, son of Alexander McIntosh and Grizel MacNab, b. 9 May 1764 Moulin Parish , c 11 May 1764 at Dunkeld Perth, alias Mackintosh, married 2 Feb, 1784, Isobel ( or Isabel ) Cameron b. 22 Aug 1764 and christened, Moulin Parish, 25 or 26 August 1764, daughter of James Camron ( or Cameron ) and Elspeth Fergusson. From this marriage there appears to have been five children, Isobel b. 19 Nov 1784, Patrick b. 15 January 1786, Alexander b. 14 September 1788, Janet chr. 02 September 1792 and William b. 30 December 1795, all in Moulin Parish.
( From here I have physical proof by way of Census and Church record copies )
Alexander McIntosh b. Redgorton ( Dull ) Perth 14 September 1788 married Elizabeth ( Ann ) Stewart b. 9 Jan 1802 Blair Atholl, the daughter of Alexander Stewart and Jane MacLauchlane. The marriage took place about the 20th of May 1821, These individuals appear in the 1841,1851,1861 Scottish Census and the Dunkeld Church records, and had issue John b. 24 May 1824, Peter b 23 Feb 1825, Henry b 1832, Alexander b. 25 Mar 1833, Gordon b. 01 Jun 1834, Charles b.18 Feb 1837, Elizabeth b 1840 and Neil b. Oct 8 1842 at Redgorton. ( copies of the above names census's and the Old Scottish Parish records are in hand showing the family )
The 6th son, Charles Mackintosh alias McIntosh, son of Alexander Mackintosh , sometimes McIntosh, was the father of Gordon ( Scotty ) McIntosh, born Scotland 1861 who immigrated to Allen's Township, Scott County, Iowa presumably sometime around 1860-1870 ( shows up in the 1870 census, 6th ward of Davenport, Scott County Iowa ) along with what appears to be his kinsmen ( perhaps cousins ), Duncan who was born in 1833, and Frederick who was born in 1846. Both living near Charles in Iowa. The witness at the marriage was Gordon McIntosh who was Charles's brother and the man he named his first son after.
Gordon, Charles son, was my G.Grandfather. I have documentary info to the time of Charles and Gordon's father, Alexander who was born 1788, but before that the details are sketchy at best and most early info came by way of the IGI or from what I could gather from the census and marriage info.
At this point I feel like I am at a brick wall as John seems to be the likely candidtate for Alexs father but I can't find proof.
