The biography of Christopher Slade is given in “Genealogical and Biographical Record of Baltimore City and County” published in 1897. Typical of most county histories published around that time, it is mostly accurate on the living people it covers and in many cases, including this one, has factual errors about their ancestry.

As it relates to Christopher's biography, it is his own ancestors who "have made (Baltimore and/or Harford County) their home since Revolutionary time". Ezekial in fact was born in America and was the grandson of the immigrant of this line. Maria's Carlin ancestor, on the other hand, was the more recent immigrant.

Nonetheless the biography makes interesting reading and is accurate insofar as the names mentioned:

"CHRISTOPHER BLADE was born June 12, 1825, on the old family homestead in the seventh district, where he still continues to reside, a highly honored and respected citizen of the community. His parents, Christopher and Delilah (Creighton) Slade, were also natives of this county, and had a family of seven children, namely: Asbury, now deceased; William; Christopher; Abraham; Creighton; John T, deceased; and Ann. The great-grandfather, Ezekiel Slade, was a native of England, and during colonial days emigrated to America, becoming a large land owner in Maryland. Abraham Slade, the grandfather, was born in Harford County, and at the time of his death also owned considerable property. Three of his sons, Christopher, John and Abraham, were brave soldiers in the war of 1812, valiantly fighting to establish the rights of our free and independent country. The first served as sergeant and the last-named held a captain's commission in that struggle.

Mr. Slade was joined in wedlock with Miss Maria E. Carlin, February 8, 1853. She is a native of Baltimore County, where her ancestors have made their home since Revolutionary times and where they successfully followed farming. To Mr. and Mrs. Slade were born eleven children, of
whom the following are still living: William, Zipporah, Columbus C, Mary, Asbury, John R., Bettie W. and Carl. As the children have left the parental roof Mr. Slade has given to each an excellent farm, but is still the owner of over four hundred acres of valuable land.

The Democratic party finds in Mr. Slade an earnest and stalwart supporter, and he has always kept well informed on the issues and questions of the day. He ranks among the most honored counselors of his party in the community, and his opinion and advice are often sought on important questions relating to local politics. In 1879 he was elected to the Maryland Legislature, in which he served with distinction for two years. For the long period of fifteen years he has been trustee of the seventh district and is recognized as one of the most popular and influential citizens of the locality, with whose interests he has always been prominently identified. He is a pleasant and genial gentleman, of high social qualities, and has a most extensive circle of friends and acquaintances, who esteem him highly for his genuine worth.

Mrs. Slade, a most estimable lady, is a faithful member of the Bethel Presbyterian Church."
