There were thousands of Mormon Elders in the 1840's, and since the name Andersen is very common, it is quite probable. The ordination records are not generally available to the public, but you may be able to get access to them by contacting the Church History Department in Salt Lake City.

In 1840, the president and prophet of the Church of Jesus Christ of Latter-day Saints (commonly called the "Mormon" Church) was lead by Joseph Smith, Jr. He organized the Church in 1830 and was murdered in the summer of 1844.
The Church of Jesus Christ of Latter-day Saints (the "Mormon" church) was officially founded on April 6, 1830. Many would consider the period between 1820 and 1840 to be the founding years of the church.
The Church of Jesus Christ of Latter-day Saints (the "Mormon" church) has always accepted people of color into it's membership. It did not allow black men of African descent to be ordained to the priesthood for a period between the 1840's and 1970's. The church has never given an official reason. I cannot speak for the Presbyterian church.
Nowhere. The Church of Jesus Christ of Latter-day Saints (the "Mormon" church) has outlawed the practice of polygamy amongst it's members since 1890 - even in nations where polygamy is legal. Any Mormon man found to have two wives (no matter where he lives) is excommunicated from the church.
The Church of Jesus Christ of Latter-day Saints (the "Mormon" church) purchases the land that it uses to build churches, temples, and other buildings or uses as welfare farms, etc from the landowner. Some of the land owned by the Church in Utah is theirs simply because they were the first people to settle and develop it in the 1840's and 1850's - there was nobody to buy it from at that time.
No, Mormon men do not have two wives. Members of the Church of Jesus Christ of Latter-day Saints (commonly called the "Mormon" church) may have only one wife (or husband) at a time. In the case of divorce or death, Mormons may remarry. So, a Mormon man might have two wives in his lifetime, but not two wives at the same time. For a period of time between approximately 1840 and 1890, the Church allowed the practice of polygamy (having more than one wife) as it is practiced in the Old Testament of the Bible. However, since 1890, any Mormon found to be practicing polygamy has been excommunicated from (kicked out of) the church. There were some who were angry with the 1890 ban on polygamy who formed their own breakaway groups. These people often call themselves "Mormon Fundamentalists", but they are not affiliated with the Mormon Church in any way.
The "Anti-Mormon Party" began in the 1840's in Nauvoo, Illinois. It was a local political party for several years.
