Brian,
The idea of a single or correct spelling for a surname or a place name is very much a recent phenomenon and before that, especially in Ireland, there was no consistency. Names were spelled phonetically and each variation was down to the whim of the particular person (often an official) recording the information. With family names you will see the spelling change all the time as the records go back. This rarely indicates a particular deliberate decision to alter the spelling. Not everyone was literate, but even when they were, exact spelling simply wasn?t something they bothered about. In addition to varying the actual spelling, acquiring/dropping O? or Mac prefixes was also very common.
Henry Simmons year of birth is a typo. Correct year should read 1834. I can add that his date of death was 2nd June 1908 and that the executor of his will was Wm H Simons, farmer. The estate was valued at ?171. 2. 6d. (Info from National Archives in Dublin). You can get a copy of the will from Nat Archives. Cost is I think ?15, but there are further fees if you want a copy of the document summarising his estate. http://www.nationalarchives.ie/index.html (e-mail them and they?ll confirm whether they have the will and the cost for copying it).
Taking into account the children you have mentioned, it looks to me as though there were at least 7 children to this marriage. I can see what looks like Isabella?s birth registered in Cootehill Apr ? Jun 1884, Vol 3, page 156. John?s was Oct ? Dec 1888 Vol 3, page 121. Anne?s was registered in Cootehill 1872 Vol 8, page 200; Jane in 1874 (in Cootehill, Cavan, not Monaghan) Vol 8, page 191; William Henry Symons (note spelling) 1875 Vol 18, page 157. I looked for William Henry Simons death. There is one for someone born 1875, in Apr ? Jun 1958 but it?s in Ballymahon, which is in another county, so I can?t be certain it?s the same man.
A townland is the smallest administrative area of land in Ireland. They can vary in size from 1 acre up to 5000 acres, though most are between 50 and 500 acres. The whole country is divided into townlands. Many are rural, and there is not necessarily any town in a townland. Indeed some have no-one at all living in them eg mountain tops and uninhabited islands. Originating in the older Gaelic dispensation, and dating back to the 11th century, if not earlier, townlands were used as the basis of leases in the estate system, and subsequently to assess valuations and tithes in the eighteenth and nineteenth centuries.
In rural areas there were no street names or house numbers (that is still the case in some remoter parts) and your townland was sufficient to identify you or get a letter delivered. The postman, and anyone else who mattered, knew exactly where in the townland everyone lived. They survive as important markers of local identity. (A townland is not the same as a US township). Corballyquill is 290 acres in size.
A parish was a group of townlands (anything from 1 to 50 townlands in a parish).
If you want to see where Corballyquill was (and still is) you can use the maps on Griffiths Valuation. It shows a map from the 1850s and then there is a slider bar facility in the top RH side of the map screen which allows you to overlay a modern map.

To find the family farm today, you need first to access the Valuation Record offices in Dublin, from which you will get a plot number. (There were around 19 farms in the townland). All the plot numbers are shown on the on-line map, so once you have found the right one from the revaluation records, you?ll be able to locate it precisely. But in general terms the farm was about 2 miles west of Cootehill, just to the north east of White Lough which is adjacent to the L2032 minor road out of Cootehill.
Re the inscription in the bible, it probably says ?Ashfield? Glebe rather than ?Asbjiela?. Rev Richard Plummer was Rector (ie Church of Ireland Minister) there in the late 1800s. See:
http://www.irelandoldnews.com/Cavan/1877/APR.html
Ashfield is in Kildrumsherdan parish. So this all fits with the family in Corballyquill.
The family of William Simmons and Ann Cootes will be harder to trace. Their marriage was evidently before 1840 and so before the start of statutory marriage registration (April 1845). Likewise the 2 children you mention were born before the start of birth registration (1864). However searching Griffiths for 1857, there were only 2 William Simmons households listed, both in Kildrumsherdan parish. One was in the townland of Killycreeny and the other in Largy. So I?d be inclined to search those same Kildrumsherdan parish records to see if your family were one of those two.
If you have any further questions, just let me know.
