You wouldn't usually find a history for something as small as an individual townland, but you can sometimes locate details on the area. e.g. Samuel Lewis' Topographical Directory of 1837, includes a listing for the civil parish which covers the area, and also mentions Kingstown

http://www.libraryireland.com/topog/O/Omey-Ballinahinch-Galway.phpA glebe is the land used to fund the local church and the immediate lessor for all the land in the townland is the Rev. Hyacinth D'arcy. The occupiers for the main property are listed as the Rev. D'arcy in conjunction with a Rev. Alexander R.C. Dallas (trustee) and consist of 'house, offices & land (orphan nursery & model farm)'. Offices is the term used on Griffith's for outhouses, workshops, stables etc.
The other properties listed are much smaller, all less than an acre, and possibly for labourers working the main farm, with their own small area to provide for their own families.
This buildings on the Reverend's property are valued at £10, whereas the other buildings are all valued at either 5 or 10 shillings, so presumably his is quite substantial and the rest have small cottages.
The publication date for this valuation is 31st March 1855, so a number of years after the famine.
You can see the townland on the 1st edition OSI maps, which date from around the mid 1830s. The Glebe house is shown, but the smaller buildings dont seem to be...
Kingstown Glebe/Ballymaconry townlandThere are still buildings in the townland about where the Glebe house was, but these are off the main road, so not visible using StreetView.
