Declan o madu lds new mission new president 2019

It seems like you're referring to a specific individual named Declan O'Madu, who has been assigned a new mission in the Church of Jesus Christ of Latter-day Saints (LDS Church) and has also been called as the new president of the church in 2019.

However, I need to clarify that the LDS Church does not publicly announce the names of individual missionaries or their specific assignments. Additionally, the church does not have a president in the sense that you might be thinking of. The church is led by a First Presidency, which is composed of three members: the President of the Church, the First Counselor, and the Second Counselor. The President of the Church is the highest authority in the church and is considered to be a prophet, seer, and revelator.

It's possible that you may be thinking of a different individual or organization. Could you provide more context or clarify what you mean by "new mission" and "new president"? I'll do my best to help you find the information you're looking for.
