Hello List, In two previous posts (Dec. 12, 2012 "COI and RC practices re: when to baptize" and Dec. 13, 2012 "Kelly-White-Plunkett RC birth-baptism intervals Kingstown 1830-1885") I listed birth and baptism dates for seven children baptized in Church of Ireland Dublin St. Mary Church between 1848 and 1860, and eleven children baptized in Roman Catholic Kingstown/Dun Laoghaire Church of St. Michael between 1830 and 1885. Here I summarize the birth-baptism intervals in the two samples. Caveats: These are both very small samples, and each comes from just one church. The COI data come from just one family. The churches were in two different towns. Especially in the RC case, the data come from a long span of time. Doubtless a priest in one RC parish or time might have had baptism practices different from a priest in another RC parish or time, and likewise for COI priests. Nevertheless, here's what I found: Birth-Baptism interval (11 RC children, 7 COI children) 0-1 day: RC 5 children / COI 0 children 2-10 days: RC 5 children / COI 1 child about 1 month: RC 1 child / COI 0 children 30-59 days: RC 0 children / COI 2 children 60-89 days: RC 0 children / COI 3 children 90-120 days: RC 0 children / COI 1 child Conclusion: In these two very particular cases, the RC birth-baptism intervals were all within about a month, and all but one were within 10 days. By contrast, only one COI interval was shorter than 30-120 days. Again, consider the caveats I mentioned above. PJ
