just sent this letter to the India mailing list at rootsweb:

My India family were in Madras, black town sometimes, secunderabad often:

Abraham HARRISON (my gg gf)
b: c1811 (unknown, possibly ireland), d: 1884 (ireland)
(Father is Samuel Harrison, possibly william samuel harrison, no other details known)
known to have been in Madras between c1840 and late c1860s

m(1): Matilda SAIRS (b: 1825, d: 1852), in 1842 (matildas parents are William and Sophia Sairs)
ch: Emily 1843, Richard James 1845, Charles Frederick 1847, Sophia Sarah 1850, Arthur Henry 1852.

m(2): Harriet Ann HODGSON (my gg gm) (b: 1840, d: 1866) in 1853
ch: Maria Alice 1855, William Edward 1857 (d: 1858), Isabella Mary 1859, Samuel Reuben 1860, John George 1862 (d: 1865), Jessie 1863, Edward c1865 (my g gf).

Abraham went to Ireland, between 1866 and 1872 with some of the children, certainly Samuel Reuben and Edward. There he remarried (3rd marriage) in Irish Town, Athlone, in 1881 and died in 1884. He was on the Lord Clive Pension so I wonder if he married to continue the pension after his death. He married a 34 year old when he was c69.

Abraham seems to have been a private with ‘A Co’ 2nd Madras European Reg’t according to a FIBIS record of an 1841 muster list. There after he was a corporal then a sergeant in the 1 Madras Regiment, and later a store sergeant, unattached list, after 1855, a pensioned store sergeant. He is noted on 2 death records of his children in 1858 and 1865, to be a Jailor. (seeking info about this)

Harriet Ann HODGSON, my gg gm, was a child of Thomas HODGSON (b: c1806, d: 1884) and Margaret MCKAY (b: betw1805-1812, d: 1878).
Both are noted to be Indo-Briton / Hindoo-Briton on 3 of their 10 childrens baptism records.
Their children were: Margaret Jane 1829, Thomas 1830, William 1832, Maria 1834, Charles 1836, George 1838, Harriet Ann 1840, Alfred Augustus 1843 (d: 1848), Henry 1846 (d: 1848), Jane 1850

Thomas was a Writer/Writers assistant/Draftsman in the quarter master generals office.
