Do you know if it is available on Ancestry as I do not have find my past. Although saying that I think I may have to go to S/P to get the actual will.
Yes. Wills are one of the sources only available from SP.
See
http://www.rootschat.com/forum/index.php?topic=714261.0As for the digitised version of the Rathven OPR at FamilySearch, when I clicked on the camera icon I got a message saying, " Images Available. To view these images you must do one of the following: Access the site at a family history center. Access the site at a FamilySearch affiliate library".
I see the family in the 1851 census at Tarrymont: William, 68, farmer; Ann, wife, 58; George, 31, son; Jane, 17, daughter; Andrew, 14, son; James, 8, grandson.
This is the family of William Geddes and Ann Mackay, who were married in Kingussie and Inch in 1813. Only three of their family are in the baptism register - John, 1814, Elizabeth, 1824 and Jean, 1833. The 'community contributed' (not to be relied on) index on FamilySearch also lists George, 1819/20, James, 1822/3, and Andrew, 1836/7. These seem to have been taken from the information on the 1841 census.
As Tarrymount is close to Enzie, I did wonder if they might have been Roman Catholic, but there are no more baptisms in the RC records.
So
IF they followed the naming tradition and
IF all the children are accounted for in the 1841 and 1851 census (not a very safe assumption) I would expect William's parents to be John and Jean. However there could have been another child or two in the gap between John and George, and some between Elizabeth and Jean.
I see that Ann Geddes, other surname Mackay, died in Enzie in 1884, aged 90. Have you seen this death certificate? If so what were the names of Ann Mackay's parents? If not, you should now go to SP and get it.
I also see that the only candidate in the OPR for William's baptism is the son of William Geddes and Ann Chapman, so it looks as if someone may have assumed that he has to be the right one. This is never a safe assumption, especially in the absence of any record of a son William or a daughter Ann.
BTW LIBINDX has a death in Boharm of George Geddes, 51, married to Isabella Thomson, parents William Geddes and Ann Kay. I think Kay is probably an error for Ann Mackay because the SP index gives his maother's maiden name as McKay.
