Pat,
Re the 1891 census entry you found (incidentally were John MCINTOSH and Maggie E MCINTOSH children of Margaret MCINTOSH, and was Maggie MCKAY a niece of Margaret MCINTOSH?) ...
Likely births of John & Maggie E in Wales, both in Neath Glamorgan, seem to be (from FreeBMD).
John MACKINTOSH born Jun quarter 1870
Margaret Ellen MACKINTOSH born Jun quarter 1872.
The IGI has LDS submissions for births in Glamorgan to an Adam MACKINTOSH & a Margaret BAIN.
There is an extracted entry for the following marriage:
Margt. BAIN m Adam L MACINTOSH, 9 Sep 1859, Petty Inverness
And an LDS submission for the marriage which has Adam Leslie MACINTOSH (age 41, parents William MACINTOSH & Elizabeth MAITLAND) and Margaret BAIN (age 25, parents Donald BAINH & Helen SANDIMAN).
A Donald BAIN married a Nelly SANDIMAN, 1824, Kiltarlity Inverness (extracted).
There are also LDS submissions about the family.
The IGI has the following births to Adam M(A)C(K)INTOSH & Margaret BAIN:
In Inverness-shire
*Elisabeth MC INTOSH 1861 (extracted)
In Ross & Cromarty
*Archibald MACKINTOSH 1864 (LDS submission)
*Adam MAC KINTOSH 1866 (extracted)
In Glamorgan, Wales
*William Lesley MACKINTOSH 1867 (LDS submission)
*John MACKINTOSH 1870 (LDS submission)
*Margaret Ellen 1872 (LDS submission - death given as 1949, mother's name as BEAN)
Perhaps Margaret (BAIN) M(A)C(K)INTOSH might have been related to Helen (BAIN) MCKAY??
