As this was sent as a general announcement, and many here were praying for her safe delivery, I give you the announcement in Katherine's own words, with one small edit to ensure the privacy of the family:
Franklin and I are delighted to announce the birth of our sixth child, Brendan Matthew Timothy . He was born here in our home on Tuesday morning, the 4th of January. He weighed 10 lb 8 oz and was a whopping 22 inches long. He has black hair.Both mother and baby are doing very well. It was a difficult birth but, God was our provider every step of the way.
Please join me in congratulating the parents and thanking God for this ordinary Miracle.
