wool_gathering's list "Navy Blue Suit" of 3 great name ideas: Mark - Philip!

Navy Blue Suit

The male equivalent of the Little Black Dress - classic, chic, versatile, always stylish, never trendy. 

Mark has the rare appeal of a strong, sleek name with a minimalist modern feel and ancient roots. The name Mark is taken from the Roman god of war Mars, also the namesake of the planet.
 After centuries of lagging behind other apostle names Peter and Paul, Mark suddenly caught on in the early 1950s, reaching Number 6 by 1960. It was in the Top 10 from 1955 to 1970 and has been among the Top 1000 boys' names for the century and a half that the US has been keeping name records.
 Mark Twain was, of course, the pen name taken by Samuel Clemens. Prominent current bearers include actor Mark Ruffalo, Mark Wahlberg (the onetime Marky Mark), and Facebook founder Mark Zuckerberg. Businessman Mark Cuban, owner of the Dallas Mavericks, is one of the main Sharks on Shark Tank.
 Marc is another, equally acceptable but less popular spelling. There are seven baby boys named Mark for every one spelled Marc.

Lawrence has survived from Roman times, when Laurentium was a city noted for its laurel trees (the laurel is a symbol of wisdom and achievement). It was in the Top 50 from the 1890s through the 1950s and the Top 100 for decades longer, always among the most popular <a href="https://nameberry.com/search/boys-names/l">boys' names starting with L</a>, but Lawrence is now used less for babies than Landon or Lorenzo. 

Nickname Lauro perks it up while Larry feels terminally dated. Loren and Laurie make it more unisex. The Laurence spelling was popularized by Sir Laurence Olivier and is also attached to fellow actor Laurence Fishburne.

Philip, the name of one of the 12 apostles, is still favored by parents in search of a solid boys' classic that is less neutral than Robert or John and more distinctive than Daniel or Matthew and has many historic, royal ties. 
 Famous bearers include Saint Philip and King Philip the Great, who was the father of Alexander the Great, plus there have been numerous other French and Spanish rulers named Philip.
 Thanks to the Duke of Edinburgh, though, Philip has a certain built-in reserve, somewhat straight and staid.
 When it comes to nicknames, you're not limited to the midcentury Phil -- more lively ones include Pip and Flip.
 The name can also be spelled Phillip; that spelling is consistently used almost exactly as much as this spelling, and in 2017 there were exactly as many baby Phillips as there were baby Philips.
 Some other modern Philip namesakes are writer Roth, late actor Philip Seymour Hoffman, architect Johnson, and composer Glass. Model Eva Herzigova named her baby Philip.
 Philip comes via Latin from the Greek and was a Top 100 choice for a century, before fading in the late-1980s. In literature, Philip Pirrip is the full name of Pip from Great Expectations. Other Philips appear in the novels of Jane Austen, George Eliot, and William Thackeray -- not to mention Raymond Chandler's detective Philip Marlowe.
