[Q]: Passage: The children of Joseph Smith Jr., the founder of the Latter Day Saint movement, and his wife Emma Smith, are historically significant because of their roles in establishing and leading the Latter Day Saint Movement, which includes The Church of Jesus Christ of Latter-day Saints (LDS Church), the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS Church, now called Community of Christ), The Church of Jesus Christ (Bickertonite), the Church of Christ (Temple Lot) and several other sects. Several Latter Day Saint sects, including the RLDS, believed that leadership of the church would flow through lineal succession of Smith's descendants. In 1860, Joseph Smith III became its prophet and president of the RLDS Church, although they no longer adhere to this practice. The larger LDS Church did not follow that practice, and it was led after Joseph Smith's death by Brigham Young.

[Q]: Passage: He was both a Catholic and a royalist, and enjoyed the confidence of Queen Henrietta Maria, who recommended him to Charles I as "a man deserving of every encouragement." In 1645 he tried to get the Confederation of Kilkenny to support King Charles I in the English Civil War on the grounds that their demands for full civic rights to be restored to Roman Catholics would be met. He fought with the Confederates against the Parliamentarians in 16456, and led a successful assault on Roscommon Castle in 1646. In 1649 he was imprisoned in London but soon released. After some time in France he was allowed to return to England through the pleas of his brother-in-law John Holles, 2nd Earl of Clare. He is said to have been one of the few Irishmen whom Oliver Cromwell admired, and was also on good terms with Oliver's son Henry Cromwell, although Henry refused his request to be allowed to recover possession of his principal residence, Merrion Castle. During the Commonwealth he seems to have played a careful double game- his second marriage into the Holles family put him in the Parliamentarian camp, but he was also suspected of working for the Restoration of Charles II.

[Q]: Passage: In 1873, the Hoylake and Birkenhead Railway was authorised to construct two extensions to its lines. One was a short connecting section near to Birkenhead docks, and the other was the extension from Hoylake to West Kirby. The station and the extension were opened on 1 April 1878 as the terminus of the Wirral Railway's route from Birkenhead Park station. The station's original signal box was built in 1886, to a London and North Western Railway (LNWR) design. This signal box was removed and replaced in 1932. After the opening of the Mersey Railway Tunnel in 1886, carriages were operated through Birkenhead Park, every half-hour, all the way to James Street station in Liverpool. As traffic increased, the line into West Kirby was doubled, from a single track, in 1896. After a board meeting on 28 October 1895, it was decided to extend the line from Hooton, into West Kirby. The station was relocated on the western side of the original station, with an enlarged island platform and rebuilt, in 1898-9, in red brick, with a turreted clock tower and mock Tudor frontage. A further platform was constructed for the Hooton line, on the eastern side of the original station. The site of the original station was used for goods sidings. In the present day, this is the site of The Concourse, a community building operated by Wirral Metropolitan Borough Council.
