Gets confusing jumping about generations, but here goes!
Regarding Grace, daughter of Grace Comb and Joseph McCluskey, have you seen that there is a border crossing card for her entering the US and destined to her sister Sarah McClusky in Brooklyn? This is from November 1912 and she shows as already married to Donald McKechie. Entry transcribed as MCKECHIAN.
So, marriage date for her to Donald McKechnie before 1913.
There are also two slightly earlier border crossings for her, with father's details showing as contact back in Edinburgh, entering the US from Canada in November 1911 and January 1912 - not seeing much of a time window for a first marriage for her if by November 1912 she showed as married to Donald McKechnie...
