Help - I can't find this answer. Which US President had the most siblings? Searched around google, to no avail. Anyone else have more luck than I?

Question

Thanks!

By Googling president most siblings, I found the first site. To check with other sources, I looked for James Buchanan siblings and James Buchanan brothers and sisters. The last site seems to be the most complete -- with birthdates and names of Buchanan's 10 siblings.
