John Maxwell Ballytober 30 acres best land [no house] so he is living in Ballywillin
11 Ballytober Townland , Carncastle County Antrim (1851)
seems to be a shared {long?}house  with  Robert Richie, note no mention of son william in the army  Robert Ritchie ‘s tenancy is listed as occupier of number 12in the continuation of [Griffiths ]valuation books eg see PRONI then Current PRONI Reference: VAL/12/B/7/4A (1863 - 1866) its page 23, on the line above is No 11 and John Maxwell is crossed out  and a john Crawford talks over a pencil note says 11b ..... illegible to me.
8 Droagh Townland , Carncastle County Antrim (1851)
Maxwell working for the Lorimer, 
1834 tithe applotment books no Maxwell found in Carncastle  {possibly because the C of I rector lived there}
Carncastle parish is bounded by Tickmacrevan to the north. Kilwaughter to the east, Grange of Killyglen to the south, the east is the Irish Sea.  Larne is only 3 or 4  miles south
The townland is along horizontal strip with a big mouthful taken out of the middle of the northern area. the nearest school killyglen national school to be found where the Ballytober road starts on the east side of runs eastwards to Brustin Bay Road and crosses over on the way to Drains Bay with road name now Tobergel Lane. Ballumullock road on the southern boundary of the townland
you can travel around ballytober road as ‘street scene’ on Modern google.  the old map 1860ish is findable at

Good luck onwards
