On deposit at the Boston City Hall Archives is a volume entitiled 'An Index to Boston Births Registered 1800 - 1849.' It was photoduplicated by NEHGS in 1990 and transcribed by Robert J. Dunkle and Ann S. Lainhart.
The notes on the source indicate:
"In the preface to the photoduplicated copy, the following comments are made: There is no title page or descriptive material associated with this index. It, in turn, is based on an earlier handwritten index that recorded family groups alphabetically only by the initial letter of the surname. The handwritten annotations in the typescript are of unknown provenance. [These annotations are so noted in the present text by italics.]
Births registered in the City of Boston for the period 1809 - 1849 have never been published. Furthermore, the City of Boston did not come into full compliance with state registration of vital records until 1849, so that the state records 1841 - 1849 are conspicously lacking Boston vital events. The present index is especially useful in that it gives the names of the parents for each birth recorded."
