Am looking for one or two marriages in Philadelphia City for:   Rudolph Robert FISCHER (FISHER) Born 21 Jun 1843 in Cannstatt, Wuerttemberg - Migrated to USA about 1856 with family. Parents: Johann Jacob Fischer & Catherina Mehl Living with family in 1860 Philadelphia Census, age 17, single - page 226. - Ward 19. 1870 Phila. Census,- Ward 19 - with a wife, Louisa, & child, Maria, age 4. In 1880 Census is in Leavenworth, Kansas with his 3rd wife, Christine, and where he dies in 1890.   Questions: Are there indexes to Philadelphia marriages from about 1865 to 1880? If so, how would I access them? Are they online or is there a Vital Records Bureau that I could write to? Appreciate any thoughts. Thanks, Renee Harris-af
