1. You could consider checking the parish records anyway. Baptisms reportedly start in 1868, only 7 years after Margaret’s birth. You might find siblings born to the same parents.
2. You could check gravestones in the local graveyards for McGuinness/McCleverty graves.
3. I saw this McGuinness widow, aged 70, in the 1901 census for Rathmelton. (She’s the only McGuinness in Rathmelton in that census). Could be a relation, I suppose, and gives you a more specific townland (address) to search. It looks to me as though her daughter Bridget McGuinness was born c 1868 and married Patrick Boyle.
www.census.nationalarchives.ie/pages/1901/Donegal/Rathmelton/Carnhill/1193189/4. I looked for McCleverty/McClaverty/McLaverty in Rathemelton in the 1901 census but none were listed.
5. I looked in Griffiths Valuation of Ireland for Rathmelton (civil parish of Aughnish) and in 1858, there was just one McGuin(n)ess household listed, in Church St, Rathmelton – Mary McGuinness at Plot 52, Church St, where she was renting a house, offices, yard & small garden.
6. There were no McCleverty (and variant) families in Rathmelton but there were some McClaverty households in the parish of Clondacaddog which is not too far away.
7. No McGuinness/McCleverty families in Carnhill townland in 1858.
