Glad to see your post and I would love to see your family History as my Family too was from the Aclare area (for lack of a better term).
I have tried to contact Nicola Howley as both HOWLEY and MARREN are common names in the area. I have and transcribed (some of) the Church Records from the LDS Files (which are hard to read) of the Church BMDs 1845 forward (much earlier than the Census).
Anyway, please post and perhaps we can exchange emails and see if we have a family link --
I know Nicola and the HOWLEY family had links with my ancestors as one married a Howley - but Nicola has not posted in a year according to the Ancestry admin.
