Looked at the record on Ancestry but just couldn't make it out but found the family in the UK 1901 Census also in Sandown and it gives Mary P Owens' birthplace as Maryboro (now Portlaoise) Queens County. Could what looks like a G in the 1891 census be a M badly written? the rest would fit with Maryboro.

The enumerator's 'M's are inconsistent but in the 1891 the initial letter is definitely a 'G'. Variable birth places is one of the pitfalls of the censuses. It makes things 'fun' though

I'll pass on Maryboro to my friend and let her take it from there.
Thank you for your help.
