Mary L Clarke married William C Brown in Clark Co. Mo. 9 June 1858. She was a daughter of William Clarke and Elizabeth Lawrence of Co. Cavan, Ireland. The family emigrated to Ontario in 1843, and after that most of the children went to USA. I am curious how Mary came to Missouri when most of her sibs went to NY; would love to hear from anyone who may recognize this family from your own tree, to share information.
