Townsley Jane Poleglass Derryaghy Antrim
with a house valued at 5 shillings pa at Map ref 14d, so you can see the outline of plot 14
within Poleglass townland on this same website. I could only find a,b,c,
https://www.openstreetmap.org/relation/4595858/history#map=13/54.5637/-6.0303on a modern map the site of 14a is 1/3rd of the way between Laurelglen Pharmacy and Woodbrooke Medical practice which is now roadsand grasss verge between the two.

Jane carries on in 14d in the continuation valuation books to Griffiths valuation see
https://www.nidirect.gov.uk/information-and-services/search-archives-online/valuation-revision-books VAL/12/B/8/2A (1862 - 1865) Jane continues
VAL/12/B/8/2B (1866 - 1876) Jane continues
VAL/12/B/8/2C (1879 - 1889) Jane continues but her name is crossed thru under 14 d with a note reads in Reps name , so she has likely just died,
VAL/12/B/8/2D (1889 - 1900) lists her name but marks it [18]90. showing no successor is named. The population growth of the area is increasing strongly.
VAL/12/B/8/2E (1901 - 1912) doesn’t include the page for 14d, as far as I could ascertain
birth and baptism records at
