Question: In what year did the current member of the United Kingdom House of Commons take affect? 
Context: The Drogheda by-election of 1880 was fought on 2 March 1880.  The byelection, to the United Kingdom House of Commons, arose through the death of the incumbent Home Rule League Member of Parliament, William Hagarty O'Leary.  It was won by Benjamin Whitworth, who had previously sat for the seat as a Liberal but on this occasion announced that he supported the Home Rule cause.  He had resigned his current seat, at Kilkenny, in order to run.  He received 382 votes as against 181 for J. McCoan, candidate of the Home Rule League.  It was reported that 150 Conservative voters had abstained in response to a circular from the party. Ian Richard Kyle Paisley Jr (born 12 December 1966) is the Member of Parliament (MP) for North Antrim, in office since 2010.  Previously he was a member of the Northern Ireland Assembly for North Antrim from 1998 to 2010.  Paisley, who is a member of the Democratic Unionist Party (DUP), is the son of the DUP's founder, Ian Paisley. Short Money is the common name given to the annual payment to opposition parties in the United Kingdom House of Commons to help them with their costs.  It is named after Edward Short (later Lord Glenamara), the then-Leader of the House of Commons who first proposed the payments.  Cranborne Money is its counterpart in the House of Lords. North Antrim is a parliamentary constituency in the United Kingdom House of Commons.  Its current member is Ian Paisley Jr. Belfast East is a parliamentary constituency in the United Kingdom House of Commons.  The current MP is Gavin Robinson of the Democratic Unionist Party elected in 2015.  Historically, the constituency has generally elected Unionist MPs, but was represented by the Alliance Party of Northern Ireland between 2010 and 2015. There was a by-election for the United Kingdom House of Commons in Hamilton on Wednesday 31 May 1978.  It was caused by the death of the incumbent Labour Party Member of Parliament Alex Wilson on 23 March of that year. This list includes constituencies created for the United Kingdom House of Commons used by Irish republicans to elect the First Dáil and those created for the Northern Ireland House of Commons and the House of Commons of Southern Ireland used to elect the Second Dáil.  Although only Sinn Féin members took their seats as TDs in the first two Dála, MPs from other parties could have done so if they wished so all constituencies used in 1918 and 1921 are entitled to be included in a list of Dáil Éireann constituencies. The Queen's County Ossory, by-election, 1886 was a parliamentary by-election held for the United Kingdom House of Commons constituency of Queen's County Ossory on 12 February 1886.  Arthur O'Connor of the Irish Parliamentary Party, member for the former Queen's County constituency, having been elected both in this seat and in East Donegal, chose to sit for the latter.  The Queen's County Ossory seat thus became vacant, requiring a by-election.  Only one candidate, Stephen O'Mara of the Irish Parliamentary Party, was nominated, and was elected unopposed.  He held the seat until the general election later that year, which he did not contest. Upper Bann is a parliamentary constituency in the United Kingdom House of Commons.  The current Member of Parliament for Upper Bann is David Simpson. The West Down, by-election, 1886 was a parliamentary by-election held for the United Kingdom House of Commons constituency of West Down on 13 August 1886.  Following the general election of that year and the formation of a new government, Lord Arthur Hill, elected member for the constituency, was appointed to the post of Comptroller of the Household, which by the rules of the time required him to submit to re-election.  No other candidate was nominated, and therefore Hill was elected unopposed.
