For All the Saints: Saints of March 6
Covers St. Baldred, St. Balther, and St. Billfrith. If the first St. Baldred was the immediate successor of St. Kentigern (d. 603), surely this profile is in error in saying that he died in 756.

Catholic Encyclopedia: Saint Balbina
There are at least two saints of this name venerated at Rome. The first, Balbina of Rome, was, according to legend, the unmarried daughter of a martyr named Quirinus, and was buried in the catacomb of Praetextatus. The second St. Balbina has a catacomb named after her.

Catholic Encyclopedia: Saint Baldred
There is a St. Baldred, a Celt, bishop of Strathclyde, b. probably mid-sixth century, and said to have been the immediate successor of St. Kentigern (Mungo) as bishop of Glasgow. Another St. Baldred, also called Baltherus, was an Englishman, hermit and priest associated with the diocese of Lindisfarne, who died in 756. Both the aforementioned saints are celebrated on 6 March. Finally, some believe that the second St. Baldred is identical with St. Bilfritt or Bilfrid, a hermit goldsmith whose work adorns the cover of the Gospels of St. Cuthbert (made 698-740).

Catholic Encyclopedia: Saints Basilides
Saints named Basilides are mentioned in old martyrologies on 10, 12, and 28 June. The first date belongs to a Roman martyred on the Via Aurelia. The entry for June 12 appears to mix up several stories, and this Basilides is most likely the same as the martyr of June 10. The third St. Basilides was a soldier or court official martyred in Alexandria, who is mentioned in Eusebius's Ecclesiastical History.

Catholic Encyclopedia: Saints Basilissa
Several saints named Basilissa appear in martyrologies. We know next to nothing about any of them except place of martyrdom, and sometimes the names of their spouses or companions in martyrdom.

Catholic Encyclopedia: Bertha
Brief biographies of five holy women named Bertha: two saints; two beatae; and one Bertha who is commonly called a saint but there is no evidence of a cultus surrounding her.

Catholic Encyclopedia: Saint Brogan
Several saints, also called Brocan, Broccan, Brochan, Bearchan, or Bearchanus. St. Brocan of Ross Tuirc was the author of a hymn on St. Brigid; he is believed to have been an abbot. His feast day is 17 September. It is uncertain whether he is the same person as St. Brocan the scribe, celebrated 8 July. Saints of this name are also mentioned on 1 January, 9 April, 27 June, and 25 August.
