Note that there are two townlands called Legananny in Co Down. One is in Drumgooland and the other in Aghaderg parish.
Legananny, Drumgooland falls within the civil registration area of Banbridge. I searched for the death of Esther Armstrong, in Banbridge 1864 to 1870 but did not find it. However 1864 was the first year of death registration and not every death was registered in the early years, so that?s not conclusive either way. Since they were apparently Church of Ireland, you may find their burial dates in the church reocrds.
Likewise I searched for John Armstrong?s death in 1873 but did not find a match. The nearest I could see in the period 1864 to 1884 was one who died 1866, est year of birth 1782. (Vol 1, page 184).
What looks to be Robert Armstrong?s death was registered in Banbridge Jan ? Mar 1889 Vol 1, page 136. Est year of birth 1818.
What looks to be William Armstrong?s death was registered in Banbridge Jan ? Mar 1909 Vol 1, page 114. Est year of birth 1822.
What looks to be Mary Armstrong?s death was registered in Banbridge Apr ? Jun 1916 Vol 1, page 95. Est year of birth 1826.
What looks like William Armstrong?s marriage to Mary Martin was registered in Banbridge in 1846 Vol 2, page 403.
What looks to be Susannah Martin?s death was registered in Banbridge Jul ? Sept 1910 Vol 1, page 80. Est year of birth 1824.

I searched for probate files for Armstrong of Legananny. I found the following abstracts (summaries):

PRONI have awill for Will of John Martin, Legananny, Co. Down. Proved 1901. D1145/B/1
Here?s William Armstrong b c 1822 with his family in the 1901 census:

There was another Armstrong farm next door, presumably relations:

Same farms in 1911:

This looks to be Susana Martin (nee Armstrong) in 1901:

Registration of births and deaths only started in 1864. Protestant marriages were registered from April 1845 onwards. Prior to that you need to rely on church records. PRONI have a copy of the following Church of Ireland records for Drumgooland but they are not on-line:
C.I. Drumgooland (Dromore diocese) Baptisms, 1779-92 and 1833-72; marriages, 1779-91 and 1834-45; burials, 1839-41 and 1860-1959.
Griffiths Valuation for 1863 lists Robert Armstrong as renting 3 properties in Legaannny. These were plots 83 ? 85 which incorporated a farmhouse, outbuildings, a caretakers house and a total of about 28 acres of land. That farm today is on either side of the Legannany Hall Rd.
Esther Armstrong is also listed that year as having plot 107 which was a farmhouse, outbuildings and 21 acres.
There are numerous Martin properties in the townland too:
http://www.askaboutireland.ie/griffith-valuation/index.xml?action=nameSearch
The subsequent revaluation records show that plots 83 ? 85 remained in Robert?s name till 1891 when plot 84 only was let to John Armstrong (the other two remaining in Robert?s name). The caretaker?s house was demolished around 1868. By 1901 plots 83 ? 85 were jointly in John & James names. They also had plot 88. John also had plots 91 & 92. The property was still in the Armstrong family in 1929 when the records finish. (There are later records in PRONI up to the 1960s but these are not on-line). VAL3 series.
Plot 107 changed from Esther?s name to William?s in 1867. (Griffiths clerks were sometimes a year or two behind in catching up with deaths and other changes of tenants). By 1901 William had plots 107 &108. Plot 107 changed to John Armstrong in 1911. Plot 108 changed from William to John to Hugh and then to John. The farm was still in Armstrong hands in 1929 when the records finish.

The tithe applotment records for Co Down are not on-line but they are held in PRONI. You should be able to use them to see who had these lands in the 1820s/30s. It might also be worth searching both the Registry of Deeds records (again in PRONI) and PRONI's general database for leases etc relating to the two families. Eg: D1503/1/13 1754-1895 Leases relating to Legananny, Co. Down
D1503/9/28Map of Legananny, Co. Down, giving names of tenants and acreages of land that each holds. The land is on either side of Castlewellan-Dromara Road. Coloured. Name of surveyor and scale not given.
D3025/E/1 c.1840
Description : Reference Book of lands in Legananny, Co. Down. It records field numbers, names of tenants, and the area of the fields, and must refer to a map not accessioned with this archive.
