Mother of John Leacock, born abt 1833, Motalee/Desertmartin

[Peggy13]

I have the death of John Leacock on Dec 13,1899 in Motalee. I have his will naming his wife Margaret and some of his children. Other research has indicated that his wife was Margaret Ewing. Children mentioned in will are John Harvey, David George, William Samuel, Kennedy, and  Emma Jane.I have found his marriage in 1867 and his father was Hugh. John was 66 when he died so born 1833ish.  I have no idea where John fits in the birth order of siblings but thinking Hugh would be born abt 1800-1810 and marriage abt 1830.
Does anyone have any information on this  family and knows who the mother of John is.
Thank you
Peggy

Religion Presbyterian. Links I am not so good at.
Death is Dec 13,1899 on irishgenealogy.ie - Age 66 so born abt 1833.
Will is listed on Proni no image but I have purchased will -Administration (with the Will) of the personal estate of John Leacock late of Motalee Magherafelt County Londonderry Farmer who died 13 December 1899 granted at Londonderry to Margaret Leacock the Widow. I can't attach will as file too large.
Marriage is Jan 15, 1867 in Parish Church at Desertmartin, his father Hugh Leacock.

I have information that there was a Hugh Leacock born 1792 in Motalee who married Sarah Jane Leacock (yes, that is  her maiden name) in 1821. If anyone has another marriage for a Hugh Leacock abt 1830 I would be interested.
Hugh and Sarah emigrated to Pennsylvania in the 1840s.
Thanks for any help
